Comcast has a digital cable service, which doesn't include any HD channels (and the box doesn't decode them as well). They also have a new HD service, which you get a new box for and which lets you watch some HD programming. I'm not sure about your area, but where I live, there are only about ten channels or so that actually broadcast in HD, so I'm waiting for more channels before I spend more money on the HD programming. If your dad has the money to blow, though, by all means tell him to get one. Especially if he likes the Discovery channel. That channel ROCKS in HD.
