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:

The last line is repeated 500 times, then I get:
stopped...
!> an error has occured.. (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.
Hi, you could try checkts, and see if the recording has continuity errors.
