There are two pieces of hardware involved. One (an Apple Powerbook)
I already have - that is the piece of hardware that does the recording
by looking like a D-VHS deck to the HDTV tuner.
The HDTV tuner is the other piece - the one I have lacks a IEEE1394
port so I ordered a Samsung T-165 yesterday.
The way it works as I understand it is you run the Virtual-DHVS
appliation on the Powerbook, press the Firewire button on the Samsung
and it thinks it is talking to a tape deck to do the recording.

Not at all. You just play the recording on the Virtual
DVHS "tape deck" back out thru the HDTV tuner. you could also play it
into the TV set if it has a IEEE1394 port.
It doesn't take a very big/fast computer to deal with ~19.8Mb/s over
a IEEE1394 connection. Now playing HD content on a computer needs
either an extremely fast computer or hardware assisted MPEG-2 decoding
(the XvMC drivers available for nVidia cards for example).
It all sounded like a lot of fun to play with - haven't actually
done it yet , that's probably going to be this weekend's excitement.
