Check out the features of the box your cable co uses. It may be able to down-convert to SD on an s-video or composite output that you can feed into a capture card (PVR150, etc.). Of course, it wouldn't be HD at that point but you'd still have access to the HD shows and the picture quality would probably still be a helluva lot better than the analog cable. I do someting like that for OTA HD using an RCA HDTV receiver.
