Hi 

This problem might not effect very many people ...

Using dvbcut with patches up to and including Michaels #11 
(not the latest from SVN)
I normally use dvbcut to save to mpg using format: 
        C: MPEG program stream/DVD (libavformat)
without obvious problems.

Today I notice that if I attempt to *recut* such a file captured from 
Channel4, saving to the same format, then I get lots of messages like:
error, non monotone timestamps 81360 >= 81360
error, non monotone timestamps 323280 >= 323280
error, non monotone timestamps 368640 >= 368640
error, non monotone timestamps 565200 >= 565200

and when I play back the smaller mpg there are many brief bursts of loud 
noise, presumably at the above locations. 

On the other hand, if I cut and save to format C as above, then recut and save 
with format:
        B: MPEG program stream (DVBCUT multiplexer)
then everything is ok.

I wondered if this was a limitation of format C (MR has previously said he and 
Sven prefer not to use it). However:
I have observed the problem only with material originally captured from 
Channel4. Other channels are fine: I can save them in format C and recut & 
save in format C and it is ok.

Was this due to a recent patch? No - I have reset the sources and rebuilt up 
to patch 6 (when support for Channel4 was added) and the problem existed at 
that time.
