#5837: crash in CC708Window::Scroll

     Type:  defect           |      Status:  new    
 Priority:  major            |   Milestone:  unknown
Component:  mythtv           |     Version:  unknown
 Severity:  medium           |     Mlocked:  0      
-----------------------------+----------------------------------------------
 I have a .nuv file (a HDTV recording of The Office, captured via a
 HDHomeRun) which can consistently crash the MythTV frontend. Several
 points in the video will crash it during normal play, but not during fast-
 forward.

 I don't see any previous reports with this stack trace. Here it is, along
 with version info. I have the video file as well; I'm not very .nuv-savvy
 but with a pointer I'd be willing to try cutting it down to a fair use
 size for anyone interested in reproducing the bug.
