I'm not, don't have a pvr-250 yet (but that's another issue).  And yes, 
I'm aware that there will be quality loss.  Just replying to your 
comment saying that I wouldn't want to do so (since clearly, many people 
do) because the quality would be "sub par"

Of course.  But there's currently no way to do that in the US.

Ah.  I stand corrected.   I just assumed that the data coming out would 
be raw DV, not mpeg.

> No. Don't confuse decoding with encoding.

oops, my bad.  I misread that (that's what I get for replying to emails 
while I'm supposed to be concentrating on work)
