 when ever watching either a live broadcast, recorded show, or avi/mkv with
 AC3 audio it sounds like a dalek or ned from southpark except even more
 stuttered.  It is only just possible to hear what is being said and is a
 really big problem.

 System:
 Gigabyte GA-G31M-S2l
 Core2 E5200
 2GB DDR800
 Software:
 Fedora 11 Rawhide x86_64
 Mythtv 0.22-0.2.svn.r20293.fc11 from rpmfusion
 a52dec 0.7.4-14.fc11
 Tuners:
 Winfast DTV2000H - primary
 Avermedia A16D - secondary

 this is a fresh install from a previous working mythdora10 installation
 where 5.1 was perfect and both tuners were working harmoniously

 I'm not sure if this is wholly related but I also get these errors
 scrolling off the screen

 this error only seems to happen when changing from a dalek ac3 audio
 stream, while not always it's more often than not.
