Encrypted HDTV to PC channels, question, required, content

andy

I am in Canada, and all cable providers here are required to encrypt all of their digital channels.  Now, I don't want to have a standalone HDTV set; I want to watch HDTV on my PC's monitor.  I have a Dvico HDTV Fusion5 Gold, but there's no off-the air ATSC broadcast I can get in Vancouver, and though the card can handle cable's QAM format, it cannot decrypt it.  I have not seen any HDTV capture card that will handle encrypted QAM.

So my question is how to view HD content on my PC.  If I subscribe to the cable company and get their set top box, I don't know how I can view the output on my computer as I don't see any reasonably priced card that will take HD component or DVI.

I've seen hardware that will modulate the output signal of a into ATSC or unencrypted QAM so then I could just use my capture card, but such hardware is either very expensive, or available as modules with lots of DIY required to make into a complete device (which wouldn't mind doing, if only there was clear information on how to put it together).

So, what are my best options?  Someone told me I should be able to connect DVI to the capture card's internal bus, but I didn't find much info on that.
