 This is simiar to problem #1960, and I have checked that the code in
 WrapTimecode is present in my build of MythTV.

 I'm off 0.20-fixes r12172. The hardware is an M2NPV-VM board with NVidia
 6150 graphics and an AM2-3600X2 processor. Currently got NVidia driver
 9626 and I've also tried enabling UseEvents in my X settings.

 I didn't enable "Use Video as the Timebase" as this appears to speed up
 the audio slightly changing the pitch.


 The error output from the frontend is as follows
