I opened a bug report (http://www.vdr-developer.org/mantisbt/view.php?id=496)
and posted a quick hack which should strip off all packets before the first
PAT and probably some packets before the first PMT (hopefully not including
the PMT). The PMT part needs to be elaborated. Sending a PMT with basic
information first should be possible and sounds like a good idea. I'll take a
look into this the next days.

Could have the same cause...
