My daughter just moved and set up her Comcast installation and was told they no longer support cable cards for Tivo because they have their own DVR. Don't they HAVE to support them? They presented the promotional rates to her if she canceled her previous account and opened a new account. If she just transferred her account, they wouldn't give her the promotional rate, but they said she'd be grandfathered with her current cable card. Does this sound right? Just curious if anyone here knew anything about that. Thanks!
