My TiVo has just told me that it has received a lineup change for channel 1 (OND). I believe this is the channel Comcast use for On-Demand programming. (Previously it was referred to as something like VODDM). I doubt if I'd be able to use it myself - I have TiVo HDs, and everything I've seen suggests the Comcast On-Demand integration would only be available on premieres. But it does look as though something is being done in the On Demand arena.
