I've been running .19, and just yesterday compiled .20 from source and
installed it on my AMD64 system (PVR-250 encoder card, running Ubuntu

The system had 4 consecutive shows to record last night, and while it
successfully recorded them, I noticed that every show past the first one
had noticeably more digital artifacts than similar shows recorded under .19
-- my hypothesis is that commflagging might have caused some contention for
CPU cycles... but then CPU power's never been an issue before, and with the
Hauppauge card, I figured I was safe from this.  (I'm recording SD content
from a DishNetwork satellite box.)

Our DishNetwork feed has been flaky of late, so I suppose I can tell my
wife that the problem was the satellite and not the mythtv setup, but I've
got my doubts.  Any suggestions on debugging?
