Home Theater PCs (HTPC) are growing in popularilty, and while you can route your TV through a HTPC with a video capture card, it's a lot of added equipment and cables. In the states, there are CableCards which allow subscribers to have the cable feed directly in to their HTPC and access all the content as if they used an (external/standard) STB (Set Top Box).
It would be great if TELUS offered an expansion card for those of us using HTPCs.
