So my basic cable was negotiated for my entire condo complex and they decided to get some deal from Comcast to get everyone basic cable. Can I add 2 cable cards to my tivo S3 with this package and add the HD package without upgrading to a digital package? I want to get the HD channels as cheap as possible. What's the best solution... I don't really need the regualr digital channels, basic and HD would be just fine by me.
