i am trying to figure this out too.  my wife is going to make me remove 
the pvr if i can't get it soon!

well, i am using regular cable directly into a pvr-250 card, and i see 
exactly the same thing.  sometimes the frontend gets locked into a 
'rebuffering' loop for 2-3 minutes, sometimes the backend gets 'stuffed 
up'.  so, although this may be a problem, its not the only case where 
this can happen.
