Well, I took the plunge into Uverse in my area. Gotta say so far, I love it. I had my house pre-wired already for networking so the install was a breeze. New cat5 from the NID to the RG, Cat5e to each STB. I also have the 6/1 HSI (just can't get full use of the 10meg service. I'm about 400 feet from the vrad and I'm on the 2nd person to get installed in my vrad.
Install tech was so glad to see I had cat5 everywhere. Says local tech dred the coax installs, just too many issues to work through and mostly lots of pulling of new wire.
During testing of the STB's I can verify that 2HD streams does work, but it was turned off as it is not ready to officially launch, but it was working great. I see others are actually being setup for 2HD streams now from reports at uverseusers.com.
HD PQ is not quite there yet, but it's pretty good. SD PQ is teriffic! DVR with 4 stream simultaneous recording has already been put through it's paces and passed the kids/wife test.
When the WHDVR functionaliy comes and the HD PQ improves a bit, it might be time to turn off my dishHD package. Sure the overall Uverse setup needs some polishing, but heck I remember how long it took dish to finally get their software to where it is today.
Also, wanted to pass along that the tech mentioned that they may be going to Cisco boxes in the future, but that is not for sure. Others have reported hearing the same thing, so who knows.
Just wanted to add my little experience with Uverse so far, honestly I am quite happy and my wife might finally be happy I stick with 1 provider for the family room for once.
