3045	Guessing avsync errors when changing channels on DVB-S	support@…	danielk	"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
