Worth another response though somewhat redundant:
1. Can a recorded program be viewed at the same time in two different locations? YES. For the cheapest package you can record and watch up to 5 shows at the same time from any TV with a Quantum box.
2. Is the list of recorded programs centralized in one list, or is the list by server? All programming is saved to the main server box no matter where the recording was initiated and is available as a single list from any TV on the system.
3. Is there any reason not to upgrade, aside from the lack of estata connection? Not any show stoppers in my opinion. The malfunctioning remote control issues have been corrected somewhat. But generally, the responsiveness to remote commands is still laggy at best. I still cannot manage previously recorded programs from my kitchen TV. I can watch them fine, just can't get the remote commands to delete programs after I watched them - have to do that from the main living room server. There are some features that did not survive the upgrade such as the Reminder feature. That's gone but may come back in future software releases.
If you need to watch recordings from multiple rooms or if you need the 5 tuner capability, then Quantum is the only servicable option. Otherwise, in my opinion the old boxes worked much better.
