Are two things you can do in this situation: Use TSPE's Direct Show Control to select the video decoder of your choice Investigate and change the default filter order to use your preferred filters using 3rd party software. Manually changing the Direct Show Filter order If you want to change the default filter order to use your preferred filters manually you will need to use a 3rd party application. There are two Freeware 3rd party applications that you can use to diagnose DirectShow filter issues: Monogram GraphStudio Codec Guide Windows 7 Preferred DirectShow Filter Tweak Tool The first is Monogram GraphStudio which is an extended version of Microsoft's Graphedit. Graphedit has been around for many years and there are many tutorials around the Internet on how to use it. However, Graphedit does not allow you to change Filter Merits. GraphStudio works very similar to Graphedit but it does let you change the filter merits. The second is Codec Guide's Windows 7 Preferred DirectShow Filter Tweak Tool. This tool is for Windows 7 and lets you change the default behaviour of using Microsoft's Media Foundation framework to allow 3rd party DirectShow Filters to be used. The first thing we need to do is investigate what is going on when we open a video file using GraphStudio.Using Graphstudio When you load Graphstudio you should see the following: The Main Screen is a canvas where we can insert various DirectShow filters and connect them together. Creating an Automatic Filter Graph First, try to load a video into Graphstudio by dragging and dropping your TS file into the main window. A Graph should appear with various filters connected to each other showing how Windows by default would decode and play back your video. For example, we'll use a h.264 video TS file: Here we

The GraphNode is a Node that may be configured with inputs and outputs and connections made between the Nodes. The GraphEdit Node is used to display a grid or blank area to place the GraphNodes on.The GraphEdit is a Container Node where its Size Flags may be set to expand it out to fill the screen. A set of Tool Buttons are provided to adjust the zoom level, reset the zoom, change the grid spacing, turn grid snapping on/off, and show or hide a panel to allow for panning around the grid. And you can pan around the grid by holding the middle mouse button.To add extra Tool buttons there is a get_zoom_hbox method to get a reference to the HBoxContainer of the Toolbar so that you may add child Nodes to it.We will use the Methods and Signals of the GraphEdit Node for all the functionality that we need. GraphNodes are added as child Nodes in the top left corner yet setting their rectangle position will not work because the container of the GraphEdit Node takes control of positioning. But, to initially place a Node, we may set its offset value. This may be based on the mouse position where we might click on a button to generate a new GraphNode. Godot 3.x Godot 4.x GDScript codevar node := GraphNode.new()get_node("Graph").add_child(node)node.offset.x = get_viewport().get_mouse_position().xvar node := GraphNode.new()get_node("Graph").add_child(node)node.position_offset.x = get_viewport().get_mouse_position().xAfter adding a GraphNode it may be selected with the mouse and moved around.Customizing GraphNodesGraphNodes have inputs and outputs called ports. These have a type specified by an integer value and connections can only be made from an output port to an input port with the same type number. Inputs are on the left side of the Node and outputs are on the right side.Control-based child nodes are added as children to create a stack of slots in the tree of the GraphEdit node. These slots allow for configuring input and output ports with a type and pin color.Note that slots are indexed by their position in the stack of slots, but ports are indexed by their enabled pin number starting from zero.To add slots, we need to add child Control Nodes. Plain Control nodes are added when they should be invisible, but set their min_size_y value to set the spacing between connection pins. These pins are displayed as dots by default and may have a color which affects the color of an attached wire (interpolated between start and end colors).We may also use any other kind of Control such as a TextureRect, LineEdit, Button etc.When a child Control Node is added to the GraphNode, an input (left side) and an output (right side) port is available and needs to be enabled in the inspector for it to show up as an available port.It’s a good idea to set up a separate scene in your project based on a Control Node and add a few GraphNodes to it. Then customize each one according to your needs. Give them names for later reference. Now

Save this scene and make it an Auto-load scene. Let’s call it “Parts”. And we should hide this scene in the ready function of our main script.func _ready(): Parts.hide()So to get a new GraphNode to add, we may do this: Godot 3.x Godot 4.x GDScript codefunc add_part(node_name: String): var part: GraphNode = Parts.get_node(node_name).duplicate() get_node("Graph").add_child(part, true) # Use a friendly node name to help with save/load later part.offset.x = get_viewport().get_mouse_position().xfunc add_part(node_name: String): var part: GraphNode = Parts.get_node(node_name).duplicate() get_node("Graph").add_child(part, true) # Use a friendly node name to help with save/load later part.position_offset.x = get_viewport().get_mouse_position().xWe can call this function from a Button press handler for example.Making connections between GraphNodesIn the GraphEdit properties, enable right_disconnects so that we may click on an input connection to disconnect a wire.When we click and drag on an output port, we get hold of a wire that snaps towards input ports that we are able to connect to. This triggers a connection_request signal that we need to connect to. And we may then make the connection in code as follows: Godot 3.x Godot 4.x GDScript codefunc _on_Graph_connection_request(from, from_port, to, to_port): get_node("Graph").connect_node(from, from_port, to, to_port)func _on_connection_request(from_node, from_port, to_node, to_port): get_node("Graph").connect_node(from_node, from_port, to_node, to_port)Note that we may connect many wires from an output, and many wires to an input. Maybe we will only allow one input connection? To facilitate this we need to scan the connection list looking for the name of our Node and the port number to see if there is an existing connection or not. So we will modify our function like so: Godot 3.x Godot 4.x GDScript codefunc _on_Graph_connection_request(from, from_port, to, to_port): # Don't connect to input that is already connected for con in get_node("Graph").get_connection_list(): if con.to == to and con.to_port == to_port: return get_node("Graph").connect_node(from, from_port, to, to_port)func _on_connection_request(from_node, from_port, to_node, to_port): # Don't connect to input that is already connected for con in get_node("Graph").get_connection_list(): if con.to == to_node and con.to_port == to_port: return get_node("Graph").connect_node(from_node, from_port, to_node, to_port)To disconnect, we click on an input port and respond to the disconnection_request signal from the GraphEdit Node. Godot 3.x Godot 4.x GDScript codefunc _on_Graph_disconnection_request(from, from_port, to, to_port): get_node("Graph").disconnect_node(from, from_port, to, to_port)func _on_disconnection_request(from_node, from_port, to_node, to_port): get_node("Graph").disconnect_node(from_node, from_port, to_node, to_port)Deleting GraphNodesTo delete GraphNodes, we need to select them and press the Delete key. We may select Nodes individually or in a group. When nodes are selected, they emit the node_selected signal from the GraphEdit Node. And when a Node is unselected, the node_unselected (Godot 4: node_deselected) signal is emitted from the GraphEdit Node.So we must keep track of the selected status of Nodes. We may do this by adding a reference to the Node as a Dictionary key with the value as a boolean indicating selected or unselected. Luckily, this is very easy to do with a Dictionary. Godot 3.x Godot 4.x GDScript codevar selected_nodes = {}func _on_Graph_node_selected(node): selected_nodes[node] = truefunc _on_Graph_node_unselected(node): selected_nodes[node] = falsevar selected_nodes = {}func _on_Graph_node_selected(node): selected_nodes[node] = truefunc _on_Graph_node_deselected(node): selected_nodes[node] = falseWhen we press the Delete key, the delete_nodes_request signal is emitted from the GraphEdit

API because many years no any problems with BDA parts. But single tuner DVB C/T devices like ASTROMETA is not typical for ProgDVB. Because 2 tuners = 2 different tuner filters. Re: Problem with HDHomeRun DVB-T #10 by EMost66Prog wrote:I am not sure about new API because many years no any problems with BDA parts. But single tuner DVB C/T devices like ASTROMETA is not typical for ProgDVB. Because 2 tuners = 2 different tuner filters.Sure! In GraphEdit I see TWO different tuners! But one for each tuner, no one for each tuner space (i.e. no one DVB-T and one DVB-C for each tuner). The problem ins't the dual tuner, the problem is the multiple tuner space support. If you read the documentation the "old" BDA API ins't compatible with some devices. The solution is use the new "Microsoft Network Provider" that is agnostic about the tuner space. Moreover, old API is DEPRECATED by Microsoft, see ... s.85).aspxI hope you can use this new API as it will be easy for you!Cheers! Re: Problem with HDHomeRun DVB-T #11 by EMost66Hi Prog,After more tests with GraphEdit I do this:1) Open GraphEdit.2) Instantiate filter "Microsoft DVBT Network Provider"3) Instantiate filter "Silicondut HDHomeRun Tuner 11111111-0"4) Connect "Antenna Out" pin to "Input0" pinAnd it works! So the problem can be the dynamic change of the tuner space incorporated in the filter. The logs show that you first try DVB-S, then DVB-C, then DVB-T and finally ATSC. So, please, can you try to use only one network provider and disable autoconfig? Or provide the option to change the order of tests (if first try DVB-T I feel the driver will initialize without troubles).I don't know where is the problem, but I feel is not very complex to fix. It's possible to generate more verbose BDA logs? Re: Problem with HDHomeRun DVB-T #12 by ProgYou can try rename device name to "xxxx - DVB-T" for force DVB-T using. Re: Problem with HDHomeRun DVB-T #13 by EMost66Prog wrote:You can try rename device name to "xxxx - DVB-T" for force DVB-T using.Hi Prog,Where I can rename it? In ProgDVB all options are disabled... I only see "{BDA} Silicondust HDHomeRun Tuner" and "{BDA} Silicondust HDHomeRun Tuner" and only enable/disable checkbox is available.Please, help me to enable this device!

How is this possible?I dont really know what you're trying to ask here. You installed a file called lame.ax. Inside this file is a directshow filter called "LAME Audio Encoder", which according to your logs is correctly being used. The older version of this file had a filter called "LAME MPEG Layer III Audio Encoder" so GB-PVR checks both names.
