As you can see his computer gets HDTV through cable (Shaw) and his Media Center (he uses SageTV which is MCE's only real competitor) can actually make the Shaw box change channels... whoa!
Can you explain a bit more how he's doing this and why we can't do it on Rogers? Does he have a "component HD capture device" that you mentioned previously, or is that built into his Shaw box and lacking on the Rogers ones?
EDIT: I just noticed a post from the author of the video, he says: "I use ATI Theater 650 tuner cards for analogue capture, and use Firewire video capture for the digital/HD channels. Getting the Firewire to work perfectly is not an easy process, but doable with plenty of patience and frequent reference to Sage TV's uer forum :)"
So my question is somewhat answered.. a bit... but I'm still confused about how his PC is controlling the cable box... and how exactly he is using firewire, i assume the shaw box has a firewire port? Do the rogers ones?
