Problems with some mythtv videos

[marsupilani]

I can't play some videos from mythtv (recorded via DVB-T) in vlc 1.1.7 with windows mediaplayer I can view them without problems. I have downloaded them locally without problems but I can't play them locally,too. I can play other videos from the same mythtv-server also recorded via DVB-T via streaming and locally without problems!???
When I try to play the first ones (locally!) I got the a lot of messages like:
...
ts warning: discontinuity received 0xf instead of 0xb (pid=392)
ts warning: discontinuity received 0xb instead of 0x0 (pid=392)
ts warning: discontinuity received 0x0 instead of 0x2 (pid=392)
ts warning: discontinuity received 0x2 instead of 0x1 (pid=392)
ts warning: discontinuity received 0x1 instead of 0x8 (pid=392)
ts warning: discontinuity received 0x8 instead of 0x2 (pid=392)
...
Same Problem with linux and windows vlc player and I see only the first picture. I'm not able to spool forward. With the other videos I hadn't this problems.
I don't understand why It work with most of the videos and it don't work with a few videos from the same source.

Edit:
All problematic videos are recordings from Pro7 so far. Recordings from other senders before and after hadn't any problems when playing with vlc, maybe a "protection" by pro7 in the stream from sender, because they spool forward or backward with windows mediaplayer.
With Videos from other senders I can do this in vlc.

Does anyone have infos about this?
