Does the new Roamio support 2 way communications with the cable card so that on demand and PPV can be used with the cable company ? On TiVo's site they list on demand as a feature, but what do they qualify as such as they link that I think to comcast cc info? Would this depend on the cable provider for support off of such? I my case it Mediacom who is currently deploying re-branded TiVo Roamio boxes with Mini's look multiroom viewing which have on demand and PPV buying capabilities so I know it technically possible but I'm not sure how my cable company has changed the original TiVo to accomplish such but they do claim theirs will not function with regular TiVo s for example MRV so if that's true there's no telling what else they changed to make (I'm not sure if they know a lot about normal TiVo's so I'm not taking their word for it). So are there any Roamio owners out there that can comment on being able to do on demand and PPV content when they haven't been able to do such on older TiVo boxes?
