Comcast on Demand on a Tivo HD??

I currently have a Tivo Roamio and a Mini in our house that both get Video on Demand from Comcast on both. I'm thinking of replacing the last Comcast DVR with a Tivo HD that has never been used and is still in the original box.



Will I be able to view Video on Demand on the HD or should I just go buy a Roamio basic?
