I am curious to know - I've seen many references to stuttering and wondering
if that's what I have sometimes. For me it's more of a chirping as people
speak, like the sound signal is partly mashed or clipped. The video signal is
OK. It seems to happen more during football games when the colour guy uses
the telestrator, but even happens on shows from PBS. I only have SD over
cable, through my PVR-550. It's not from CPU saturation - I'm never over 40%
on playback. I have audio buffering stuff turned on in Myth. I optimize my
database weekly. I have Google but nothing definitive.
