The second one on the list - MPEG program stream (dvbcut muxer)

I noticed that, too - ProSieben seems to send a lot of broken PTS'.

I'd rather expect that the player chokes on the bad timestamps, not on
the corrected ones.

But maybe something else is wrong with that stream.

Really? Then it might be a buffering problem.

That's caused by a damaged or missing macroblock (MB) in one of the
pictures, i.e. a transport error.

Oh well, yes.

Yes - after a while, some sectors of a DVD+RW (or DVD-RW) may become
unreadable. And although some vendors claim that you can overwrite their
disks up to 1000 times, I haven't seen any yet that survived more than
20 cycles.

You may want to check your syslog for error messages in that case.
