I would probably go with this one.
Canadian Prices: MSI Computer - MSI TV-TUNER CARD,THEATER 650 PRO, PCI-E, RETAIL - THEATER650PRO
It's PCI-E and should come with it's own software and also works with Windows MCE.
AFAIK you are not going to be able to find anything that can do any of the following:
- Can watch Rogers Digital TVs (the more channals the better)
- Can get Rogers HDTV
- Can hopefully decrypt Rogers TV so i can watch all the channals for free
