[mythtv-users] choppy, decoding errors

[dave sailer]

I have had a pvr250 for some time and recently started having problems
with choppiness/slowdown. I see the following out of mythfrontend....

I believe I have always gotten the error "Couldn't get the color key
color, and we need it.
You likely won't get any video" and it didn't seem to be a problem.  I
did recently install another pvr150 but it was happening before that. I
get it with live tv or watching recordings thru myth. If I watch
recordings thru mplayer, I don't have this problem.

here is output from dmesg...
