Comment(by anonymous):

 I is possible that we have 2 different things here:

 - One thing is the judder when playing HD channels with Life TV (for me
 with Anixe HD and Astra HD). I have no judder when playing a recording of
 these HD channels. For me it is not so important (who is looking LiveTV
 ;-)).

 - The other thing is the problem with current (german) 720 p channels Arte
 HD, Das Erste HD, ZDF HD and EinsFestivalHD. What I can see here that I
 get to little frames. When starting mythfrontend with -v playback I can
 see only 42 fps and not 50 fps (720p at 50). So the video must jump to follow
 audio? I have recordings from EinsFestivalHD with same content from
 09/17/2009 (OK with 50 fps) and 01/11/2009 (not OK, 42 fps not constant).
 I am sure that "they" have changed anything on the codec-parameters. This
 problem is important because I cant watch the recordings. But I can watch
 it with mplayer.

 Last weekend I have checked all my satellite stuff (cut the trees, change
 the LNB, update direction ...). But the problem is still there. Until that
 I have found this ticket which partly described my important problem.

 Note:
 - In my test-system I use MythTV 0.22 with the effects described here.

 - In my "production"-system I use MythTV 0.21 and since some weeks the
 frontend hangs on playing content of the HD-channels like Arte HD, Das
 Erste HD and ZDF HD. Anixe HD and Astra HD works fine. I have seen this
 effect by the testloop of EinsFestivalHD before. But at the time of last
 showcasts (WM and IFA) all works well.

 Hope it helps.
