Advertisements I'm thinking about taking the plunge and getting a series 3 Tivo for use with my Comcast setup. This would be replacing my Motorola 6412 Phase III which actually isn't that bad. However, what's the latest news on the Comcast Tivo Brand DVR? Any news as to when this will be released? Also, is it true that OnDemand will not work with the Tivo S3?
