TiVo and Comcast

We have just made the switch from DirecTV (satellite) to Comcast (cable). We have taken advantage of Comcast's offer to save money by getting our Internet, phone and TV cable from them. While I was spending more than hour on Wednesday evening on the phone with TiVo technical support to make the TiVo work after the cable guys fucked it up, Mr. D had me ask if TiVo was going to be able to use our new digital phone line to load information. The answer was a definitive "no."

Shit!

We can use a wireless network to load the info but Comcast's modem didn't come with one, like our Verizon DSL did. It is possible to use the Internet but we haven't figured out what that will entail -- bringing the modem upstairs and plugging it into the TiVo every week? I have no idea.

So the TiVo person says, TiVo is not compatible with Comcast's phone line (of course they're not they don't want people getting Comcast because Comcast has it's own DVR that is easier (all one box/remote)). But Comcast's website says it does work with TiVo. Does anyone know for sure if a digital phone line will work with TiVo Series 2 or will we have to figure out how to use the Internet with it?
