I tihnk its area-specific. When I had an HD DVR, it was only $12-13 a month.
Indeed, it is area-specific. Our regular DVR with Comcast was $18/mo.
I actually said screw that and got the TiVo
with the 2 CableCARDs, it's $1.50/month for both of them, but you get a credit of $3.65 for each card you have for not using their equipment, so it's a $7.30 credit to your account. Now, the tivo is $12.95 a month, so subtract that credit, it'll cost you approx $5.65 to use a TiVo instead of their HD DVR. Think of the savings!
I probably could have explained this better, but I'm side tracked at the moment.
