 (Trunk 27105, Ubuntu 10.04, PVR-500)

 Right, this problem started appearing for me about two weeks back in
 trunk. I am honestly not sure which rev i was on before. (And I am not
 sure if it is possible to check?)

 I mulled it out on the users-list, but didn't get any applicable feedback,
 so I decided to give it a trac-run.

 The problem now is that in most "scene changes", as in if the show goes to
 "all black screen" or you come "in or our" of a commercial... Or even
 moving from one commercial segment to another, Mythfrontend just crashes.
 Not all recordings behave this way, but I would say that all recording
 from some channgels DO behave this way. (THey are all recorded from the
 same STB to composite on the PVR).

 Below is a log dump of me starting to watch a recording, until it crashes.
 SOmetimes (very rarely) I also see

 "pure virtual method called
 terminate called without an active exception
 "

 Anything I can / need to do to help with more info. Let me know.
