The dual is basically the lite and usb on a single card. One PCI device
and another USB (when you connect the cable).

Not a lot. I was originally concerned as I intended to run it in a lower
spec'ed machine. As far as I know with digital tv the card just has to
write the stream to disk, where-as with analog tv it needs to be encoded
(Hopefully someone will correct me on this)
My Athlon 700 can record 2 channels using about 25-30% cpu. It's the
playback the requires a fairly decent machine. My 1.4M laptop plays SD
back fine, but skips when playing HD content.
Hope this helps,
Simon
