Description
I have this issue since long time (I believe it appeared as 0.27 release times). I happens randomly (once per 10 or so livetv channel or program changes) and I can catch this only on Nvidia gfx
Symptoms:
when user is changing livetv channel - sometimes new tv channel playback is looped image. (see on link with video). Around 0:06 new channel should start to show its content - but instead old channel looped images are going.
Issue can be seen also on program transitions in livetv history: around 0:00:19 user asks to jump to livetv previous program. Around 0:00:21 old program is displayed; around 0:00:25 - after program transition there is again looped image
MOV video with issue: http://warped.homenet.org/looped-playback.mov
FE log looks like below. I'm ready to recompile FE with added logging/debugging code.
mythtv is current master. Distro is minimyth2.

Peter, I lost faith will anybody look at this ticket so I deleted file. Sorry for that! File is here http://warped.homenet.org/looped-playback.zip
The whole issue is interesting as it has kind of historical memory. I need to enter TV channel from particular set of liveTV channels if I want to trigger issue in future.
Namely: walking on any 1080i H264 channels - no problems.
To trigger issue I need:
1.Enter any SD H264 channel from exact multiplex1
2.Enter HD H264 channel from exact multiplex2
3.Enter HD H264 channel from exact multiplex3
Only such combination triggers issue.
Key seems to entering any SD H264 channel from exact multiplex1. Without this steep I can walk on all 60+ HD channels no problem.
Issue is only on Nvidia with Nvidia closed drivers. All works OK on Intel VAAPI and ATI Mesa VDPAU. On Nvidia it seems to not dependent on Nvidia BLOB version (tested legacy & current versions) nor HW (tested ION, ION2 and GT610M).
I believe it is result how MythTV uses VDPAU on Nvidia drivers as I remember situation when gigem was updating scheduler on master. In that time there was short time window with bug about how LiveTV channel change works within the same mplex (mythtv was changing channels within the same mplex like between different mplexes). With this bug looped issue disappeared. This suggest me that issue is somehow timing related...
Maybe we should made tests with mod where LiveTV channel change resets VDPAU on every channel change?

It looks like it is getting an error decoding every frame after the channel change. Then because frames are not decoded it is playing what is left in the buffer and that is the last few frames over and over.
In your output you can see it is calling InitVideoCodec after each channel change. This proves it is already resetting VDPAU each time, as you suggested. Also after the InitVideoCodec log message you can see "Opened codec 0x2cd9ee0, id(H264) type(Video)" each time.
I wonder if the codec is closed before being opened again. There is no log message for closing codec.
I cannot test your situation because all of my channels are encrypted and I cannot switch channels to the same multiplex without complete retuning being done. Also we have only 720p H264 channels.

I found channel change combination giving me 100% reproducible issue. Below is log from channel change across 4 channels and last change ended with looped playback.
