I have no samples that I can share on this subject.
Do you have MPEG2 decoder software on your machine? You can't hook MPEG2TS
output to VMR. It has to go via MPEG2 Demux and MPEG2 A/V Decoders.

Hi Max,

Thanks for your suggestion!
I change my code in the way your suggested:
static KSDATARANGE StreamFormatMPEG2_Capture =
{
// KSDATARANGE
sizeof (KSDATARANGE), // FormatSize
0, // Flags
0, // SampleSize
0, // Reserved
STATIC_KSDATAFORMAT_TYPE_STREAM, // aka. MEDIATYPE_Stream
STATIC_KSDATAFORMAT_TYPE_MPEG2_TRANSPORT, //MEDIASUBTYPE MPEG2
TRANSPORT,
STATIC_KSDATAFORMAT_SPECIFIER_NONE // aka. None
};
Now, capture pin can be connected with MPEG2 demultiplexer. But when I "run"
the graph, an error message is shown: "The graph could not change the state".
The return code is 0x800706f8. It means user buffer is invalid.
Why?

What is your graph topology?
Output A/V pins of the demux are connected, aren't they?

Now it is time to put some breakpoints in your pin handlers and make sure
that state transition is handled correctly.
