The Dish Network PVRs hardly have the same capabilities as TiVo. Really, they aren't nearly as feature rich. As for the channel changing thing - actually I know I've seen that come up in the support forums on TiVos website, did you search their support knowledge base and forums? A search on 'Dish Network Timeout' - first search I tried. A couple of good hits - one which ultimately leads to this, which has been posted here and all over a number of times. Very good resource. As for the number of tuners, the prototype HD standalone box has two digital cable ready tuners and two OTA ATSC tuners, with any two being usable at a time (similar to the HD DirecTiVo). Whether or not the final unit will be that way - who knows. If they can go with CableCard 2.0 they could, in theory, support 5 channels at a time on one CableCard 2.0 tuner since it should support multi-stream. But if you need to have multiple hardware tuners in a box, then the box will cost more than a single tuner unit. The DirecTiVo units, and the cable boxes with dual tuners, are heavily subsidized by the carrier. Since TiVo said they're going to introduce a service commitment sales option (like DirecTV, cell phones, etc - lower priced hardware if you agree to a minimum term of service) perhaps they can handle it that way.
