I used these instructions to configure the RTC for high resolution timing:

/dev/rtc0 is the device that mythfrontend used on my system. /dev/hpet 
wasn't used so there was no need for me to configure it.

Hey, this sounds very promising. I'll be looking forward to trying it. 
Fedora 19 uses kernel 3.10 and Mesa 9.2 but it looks like Fedora 20 is 
going to use kernel 3.11.

I've just tried out the VAAPI Normal playback profile. The video plays OK 
but the deinterlacing is pretty ugly: lots of horizontal lines while the 
video is in motion. I then went on and tried out High Quality again. 
Apparently I hadn't tried it since I enabled RTC video timing: it looks 
very good now. High Quality uses the Yadif deinterlacers. VDPAU locks up 
mythfrontend just as before.
