Thanks for the responses, David and Mike.  That's good to know.  What
would the quality loss be if I upgraded to 0.25 and switched from
hardware decoding to CPU decoding?  The CPU a 2.8 GHz Pentium D.

For the immediate problem, is there anything I can try?  It appears
that my ability to record programs is completely broken, and in
addition to only recording 15 minutes of the first program, each of my
test recordings has only had sound for the first 10 seconds and then
it cuts out.  Would a downgrade to 0.23 be worth a try?  Also, could
this be a symptom of overheating the capture card?  Just curious,
because this PC is a BTX design with mostly passive cooling, so it
probably has poor airflow.

I was really hoping to avoid buying a new tuner card, but if it comes
down to that, do you have any recommendations for Nvidia cards?  I'd
love to get one with hardware encoding and decoding like the PVR-350
if possible.
