I got excited after reading this post and connected my ATI Digital Cable Tuner to my Windows 7 Premium PC only to be told (like I was back in Vista) that my PC was not Cable Card ready.   I installed my tuner, updated to the latest firmware, but when I went to add the tuner to Media Center I got the dreaded "Your computer is not digital cable ready" message.    Thinking this was wrong based on the article above I opened a support ticket with Microsoft only to be told that the OEM had to pre-enable this feature for it work.   Sigh.
