Hi, Running VDR 1.6 on a FF and Budget cards I have problems with recordings made from the channel ITV3. The video itself starts OK, but gets very jerky after a while. Restarting playback makes it better for a while. Sound gets more out of sync with the picture, its also better after restarting playback. I tried replaying on VDR 1.7 and the problem was the same. I tried demuxing the recording with ProjectX, this was the output: <<< session infos >>> Monday, March 26, 2012 4:32:41 PM CEST ProjectX 0.90.4.00 (30.03.2006) -> working with collection 0 -> save normal log file -> write all video data -> write all other data -> patch c.d.flagged infos of pictures -> add sequence end code -> set resolution in SDE -> PVA: strictly specs. for audio streams -> VOB: determine diff.

Hi, you could try checkts, and see if the recording has continuity errors. http://projects.vdr-developer.org/git/vdr-checkts.git/tree/README Joerg
