Description
Danish broadcasting closed down the analog signal and started 3 new channels with HDTV signals. I can't play these new HDTV streams without extreme jerking of the whole image - in seemingly backward and forward motion. I am running Ubuntu 9.04 64-bit, MythTV trunk 22760M, CPU is Ahtlon 64 x2 4400. I was running XV, but now switched to VDPAU (8400GS, 256MB) and its the same. I tried following patch: http://svn.mythtv.org/trac/attachment/ticket/7252/mythtv_decoder_reorder_pts_v3.diff
and setting VDPAU buffers to 40 according to info in http://svn.mythtv.org/trac/ticket/7405
- but no luck.

I have the exact same problem. It is not limited to the HD channel, but to most of the new h.264 channels. I have attached a log output for my configuration (it might differ from the original ticket creator). A sample file is available here
Additional info: mplayer produces similar error messages and behaves exactly like MythTV. VLC plays file perfectly. ffplay (svn trunk) behaves like Mythtv ffplay -strict plays file perfectly
Configuration: Athlon XP 2400+, Nvidia 5200FX, Ubuntu 9.10, mythtv-0.22-fixes

I have the exact same problem. I had problems with all new h.264 channels in DK but after ver. 22722 some of the channels (DR K and DR Ramsjang) started working. Let me know if I need to post some example video

It is true, that DR K and DR Ramasjang work fine now - at least most shows. DR HD is still bad. I am not sure if they changed the format on 2 channels - they are not really HD channels, but EPG says the shows are in HD.
I don't think MythTV changed - but I guess its easily tested. I will check when I get the chance.

Same problem here with MythBuntu? 9.10 plain install, mythtv ver 0.22.0+fixes22594-0ubuntu1
Don't know if this is made clear, but the new channels are mpeg4 h264 channels in dvb-t with aac audio, most channels are 720x576 and one 1280x720 pixels.

The latest patch (mythtv_ffmpeg_r20504.diff) fixes this issue for me as well. Could this please be commited, so we danes aren't forced to patch every new version.
Thanks in advance and thanks for the patch.

Please have a look at Ticket #7481. There is also a (simpler?) patch that worked for me. Maybe this is a similiar Problem. Also Ticket 6922 seems to be similar.
