A family of 5 with a couple of teenagers and three TVs in the house would hardly be considered "power users". The 5 tuners aren't just for recording, they have to support live TV as well if D* moves to a 3 C31 installation. But I agree that if each TV is being used, the net affect of tuners available for recording /watching live TV would be the same as having an HR2X with 3 receivers (ie 5 total tuners) with the added benefit of being able to pause live TV on the other TVs.
The point I was making is the wildcard is Genie. If that is a major push, there is simply not enough tuners. People will either be unable to use Genie or be aggravated because they constantly have to ration tuners in the house. Especially in the current implementation where Genie seems to take tuners as it pleases to the point it interferes with live TV.
I think anyone can find a "what if" case.
U-Verse has customers, but is limited to 3 or 4 channels.
The HR34 & C31 can share a tuner, which is nice, as the commercial for Whole Home DVR becomes a bit more of a reality, as you're not limited to recordings, but can do it with live TV.
Have you ever run out of tuners on the HR34 with a C31?
It pops up a screen where you select which recording to interrupt.
If Genie were "in my way", it would get stopped.
If the "couple of teenagers" end up putting more demand on the system, the customer can add/change them to a DVR.
You can't do this with U-Verse.
