Does anyone have any more suggestions on how I might be able to get my HD to work?

I summary:
- Thanks to Vista Codec Pack, I can now watch HD .ts files in Window Media Player
- If I try to watch an HD recording or live TV in Media Portal, I get sound but no picture
- I can record HD tv with no problems.
- Standard Definition recording and playback works fine.

Thanks in Advance

Rob

I'm back. I've been trying a few things myself, but to no avail.

I uninstalled SAF since it doesn't support live HDTV, or playback of recorded TV without changing the filename (not really an option when I want a simple solution that my wife can use).

(The following only applies to HDTV - SD is all fine)

Playback through windows explorer of the .ts files works fine. If I change the filename of the .ts to .mkv I can watch through videos in MediaPortal. Watching live TV or recorded TV through Media portal gives no picture (sound only). A screenshot of Graphstudio when playing back HDTV is attached.

How do I get it to correctly recognise the HDTV video and send it to the correct decoder.

I have installed the latest version of VCP.

Please help - my wife is getting fed up with not being able to watch HDTV without my help!

    Hi Robferrer,

    Did you ever work out a solution to this problem? I have exactly the same issue and would welcome any advice. My GraphStudio looks virtually identical to the one you posted.

    Any help greatly appreciated.

    Hi Ascott

    I did solve it (sort of) eventually. I bought CoreCodec. This didn't work at first (I could only see a corner of the image), but disabling deinterlacing seemed to do the trick.

    I should really start a ticket with CoreCodec to see if they can fix the deinterlacing, but for now I'm just happy I can watch my HD programs (and so is my wife!).

    Hello,

    I have playing with similar problem for a while and after small development I have found a partial solution. My problem is with DVB-T encoded with H264 in Poland. I have perfect audio and no video. If I start GraphEdit I can see that ffdshow is no connected to TsReader filter. I have downloaded sources and found that there is a bug in the source code of Demultiplexer.cpp. The bug is in function "void CDeMultiplexer::GetH264Media(CMediaType *pmt)".
    You should replace line:
    pmt->SetFormatType(&FORMAT_VideoInfo);
    with line:
    pmt->SetFormatType(&FORMAT_MPEG2Video);

    This function should looks like this:
    void CDeMultiplexer::GetH264Media(CMediaType *pmt)
    {
    pmt->InitMediaType();
    pmt->SetType (& MEDIATYPE_Video);
    pmt->SetSubtype (& H264_SubType);
    pmt->SetFormatType(&FORMAT_MPEG2Video);
    pmt->SetSampleSize(1);
    pmt->SetTemporalCompression(TRUE);
    pmt->SetVariableSize();
    if (m_mpeg2VideoInfo.hdr.dwReserved2==0)
    pmt->SetFormat((BYTE*)&m_mpeg2VideoInfo,sizeof(m_mpeg2VideoInfo));
    else
    pmt->SetFormat(g_Mpeg2ProgramVideo,sizeof(g_Mpeg2ProgramVideo));
    }

    The problem is that it helps only in single-seat configuration. Becouse I have separate TV-server I must develop it further. I'm not sure, but the problem is probably in TsWriter.ax.

    Przemco
