I tried adding a Sleep after all filter created.  I tried creating filter by name... I tried different DirectShowLib versions, I tried RenderStream only...
No LUCK, getting out of resources, how come the graph works, but C# code fails ??

Here's the code generated for the graph.
I have version 1.4.
The error I get is Can't connect AverMedia 7231 Analog TV Tuner and AverMedia 7231 Analog TV Audio.
Code:
static void BuildGraph(IGraphBuilder pGraph)
        {
            int hr = 0;

            //graph builder
            ICaptureGraphBuilder2 pBuilder = (ICaptureGraphBuilder2)new CaptureGraphBuilder2();
            hr = pBuilder.SetFiltergraph(pGraph);
            checkHR(hr, "Can't SetFiltergraph");

            Guid CLSID_AVerMedia7231AnalogTVTuner = new Guid("{266EEE40-6C63-11CF-8A03-00AA006ECB65}"); //kstvtune.ax

        }_

The above code crashes on the following line :
hr = pGraph.ConnectDirect(GetPin(pAVerMedia7231AnalogTVTuner, "Analog Audio"), GetPin(pAVerMedia7231AnalogTVAudio, "TVAudio In"),
Can't enumerate pins on 'Analog Audio', and the graph works when I run it... Please help Smiley

Thanks.

Those tuner filters should be created differently, code generator in GraphEditPlus doesn't know this yet.

You should enumerate filters in the category where those filters are listed and insert them via BindToObject. See

I got it working by declaring the filter using the 'Display Name' showed in the filter properties .
My concern is I'm not sure this will be the same on every machine I'm installing the software on...
I might need to include these string into a config file.
Code:
IBaseFilter pAVerMedia7231AnalogTVTuner = CreateFilter(@"@device:pnp:\\?\pci#ven_1131&dev_7231&subsys_06071461&rev_aa#4&25ba7335&0&00e1#{a799a800-a46d-11d0-a18c-00a02401dcd4}\{62b08a3e-335e-4b30-90f9-2ba400000000}");
            System.Threading.Thread.Sleep(100);
            hr = graphBuilder.AddFilter(pAVerMedia7231AnalogTVTuner, "AVerMedia 7231 Analog TV Tuner");
            checkHR(hr, "Can't add AVerMedia 7231 Analog TV Tuner to graph");

Example above.
Thanks.

Here's the code GEP generates to create filters by name:
http://forum.infognition.com/index.php/topic,798.msg1901.html#msg1901

It should be more reliable than using DisplayName.
