got it on Tue., worked great, made recordings, lots of fun, an hour ago I called Comcast, how stupid of me, to complain about the On-Demand META-6 error, they tried sending a signal to my DVR, didn't worked so they reset it and asked me to wait couple of minutes before turning it on again and that it will take an hour to reload the guide.
That was the end of my DVR, never came back, nothing comes through. Called Comcast again, the rep. gave up pretty quickly and set me up with an tech appointment for Sunday morning. Power cycled it didn't helped.
Box info: SW 71.44 - 1203, Firmware: 09.12.
I'm going to try to replace the box tomorrow at their center.
My advice is that if all works grate except On-Demand don't let them reset the box, they don't seem to have enough experience with what they need to do to fix it in remote.
BTW, I had the META-6 error with their std. HD Box as well on Monday before they installed the DVR, I tried explaining them that the DVR might not be the issue but it was like "we do this all the time and it works". What irritates me is not that this is a new technology free of bugs but the fact that they don't think of the consequences before doing something.
Anyway, I heard that one of the high tech executive said in a conference that cable companies infrastructure is limited and that they won't be able to compete with sat. for HDTV.
