We had Uverse 450 at my old house. I liked that it offered more HD and premium channels than Time Warner for almost the same price. The internet was great too. The only thing I hated about it was I kept having to reset my HD DVR often. I'd be watching a program and then it would freeze up. It got bad to where once a week I'd have to reset it, then one day my DVR just quit. They got me another one and it was ok for awhile then it started doing the same crap, although not as much.
My brother, who lives in the same area as me, has similar problems with his DVR from Uverse, but not quite as often. It just sucks when you friends over watching a PPV event and the damn thing freezes up and you have to wait 5 minutes for everything to reset.
I'm now back with Time Warner, but only because the area we moved to doesn't offer Uverse...the cable and DVR is trouble free, but the channel line up sucks and the internet is slower.
