To record the cable you can purchase a cable card tuner and a cable card, but it is uncertain if Shaw will activate the cable card. There are some reports of success and other that have been refused by Shaw to activate them. This option would allow you to record the digital stream as being sent by Shaw with no re-encode. Failing this, you can use a hauppauge HD PVR. For this you need a HD Cable box with component outputs to connect to the HD PVR. You loose some quality as there is an analog link and you are re-encoding. Early HD PVR's were problematic and easily overheated. I suggest you check The Green Button forums to verify what models work with the fewest problems.[Link: thegreenbutton.tv]
I do not use Win7 media centre myself, but do use ATSC tuners for capturing digital channels with my TV antenna.
Using a digital tuner card with no cable card will only give you very few, if any, unencrypted TV channels.[Link: thegreenbutton.tv]
The HD PVR and Colossus seems to still be buggy for media centre.
