[mythtv-users] CrystalHD playback problems

Thu Dec 22 09:30:43 UTC 2011

Replying to my own post (bottom-quoted for completeness). Let me know if 
this isn't accepted behaviour!

Anyway, I want to make a final check--is anyone else having playback 
problems with CrystalHD? Or, more specifically, a bcm970015 with an 
intel gma950?

If not, I'll assume that I'm hitting a bug here. What would be the 
proper way forward? A post to the -devel list or a bug report?
