Hi,<br>
Running VDR 1.6 on a FF and Budget cards I have problems with
recordings made<br>
from the channel ITV3. <br>
The video itself starts OK, but gets very jerky after a while.
Restarting playback<br>
makes it better for a while. Sound gets more out of sync with the
picture, its also<br>
better after restarting playback. I tried replaying on VDR 1.7 and
the problem was the same.<br>
<br>
I tried demuxing the recording with ProjectX, this was the output:<br>

The last line is repeated 500 times, then I get:<br>
<br>
stopped...<br>
<br>
!> an error has occured.. (please inform the authors at
'forum.dvbtechnics.info')<br>
java.lang.NullPointerException<br>
<br>
<br>
Is there any way I can analyse this further? I dont see any errrors
with femon on ITV3.<br>
<br>
