Comment(by anonymous):

 It seems to be a (H264-)decoder problem because CoreAVC-Decoder works fine
 (when porting to MythTV 0.22). But on the other side the H264-decoder-
 sources of Myth0.22 and Mplayer are identical (last week) but mplayer
 seems to be work.

 Corious is that recordings of EinsFestivalHD from middle of september
 generates no problems but current recordings of EinsFestivalHD (with the
 same videoloop) have problems.

 Another point is that current recordings of EinsFestivalHD freeze MythTV
 0.21 completely (only kill helps). Using CoreAVC only are not enough here.
 There is the need to backport the HandleH264PrePkt of avformatdecoder.cpp
 from MythTV 0.22. This function handles among other things the GOP-
 management.

 So the idea is that changes in the parameters of H264-codec and especially
 in the GOP-management is the cause for this problem.

 If there is interest I can submit current CoreAVC-patches for 0.21 and
 0.22 and can send the recordings of EinsFestivalHD from middle of
 september and end of october. Let me know.
