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.

(please inform the authors at 'forum.dvbtechnics.info') java.lang.NullPointerException Is there any way I can analyse this further? I dont see any errrors with femon on ITV3. Cheers Brian |
