[mythtv-users] mythtv freezes during the buffer change (0.19)

I don't use the PVR-350's tv out or load the ivtv framebuffer. I'm 
actually using the svideo out on my nvidia card. Happens with the 350, 
500 and 3000. With ivtv 0.4.2 drivers and recommended firmware.

Feb 13 00:42:46 mythtv kernel: ivtv0: Decoder revision: 0x02020023

However, I enabled xv video control and it seems to have worked past the 
end of a program for the first time since 0.19 for me... I'll try some 
more with xv on and off to double check that this is the cause of bug 
and report it on trac if this is the case.

Thanks
