not being a firewire user this may be totally off base but why would
you think that the cable dvr is streaming you recorded programs out
the firewire? i can't imagine the tv hooks up to the dvr through
firewire. i think people are confused because they assume you are
capturing off the cable dvr's a/v out in which case you would have a
capture card capturing the output. the capture card could vary
depending on what types of a/v out you cable dvr has.

if you want to tune the current cable feed you can do that through the
firewire if the channel is unencrypted but you can't capture off the
firewire to get previously recorded video. at least that's my
understanding of the process.

hope that helps!
