The videos played back with big drops in sound. The playback would start and about every 20 seconds the audio would drop off while the video played and then it would catch up again. These shows had need recorded with 0.24 and I had already watched them so I knew the files were OK. I also upgraded the nVidia drivers to the latest release and tried some other things but could not get the 1080i files to play properly. Then I looked at the VDPAU playback profiles when I recalled that I was using VDPAU HIgh Quality for all recordings. I switched the profile to VDPAU Normal and now my 1080i programs play really well.<br>

The system has a GT 520. I dropped it down to VDPAU Slim and the audio dropouts went away, but then the deinterlacer looks horrible.<br>

<p>Besides upgrading the video drivers to the latest version (350.xx i think) i also noticed from the logs that myth was using usleep for timing. I was able to get the RTC working with myth and the playback is very smooth and in sync with the sound. I do remember now though that the playback in .24 was not as smooth as it is now, I kept having to manually synchronize the audio with the video in each show. Have you tried looking into this with your system?</p>
<p> So VDPAU HQ was not completely smooth in .24 but was playable, unlike .25. The VDPAU Normal profile I use now looks and sounds great, I'm guessing some underlying library update in the OS caused the change.<br>
