My HDVR2 rebooted 3 times when I was watching a show. My wifes R10 has rebooted every day also and its has 6.4a software. The time it reboots has very little to do with it if any at all since I have had reboots watching a show, playing a show while recording on a hard drive dvd recording. I am a pretty loyal guy but I have my limits. The only reason I have not switched to another service is that At&t has one location for where the movies are stored and my wife and I need to have them separate plus the fact she has 2 inputs and I have 4, we would have to give up 2 inputs. Guess it does not matter because of my lung cancer but I am getting pretty mad and willing just to have some basic type of cable and able to record it on a large hard drive. I have a TR24 which I am not fond of as it does not have some of the features the tivo has plus I do not have high definition tv. I am leaving for Utah to visit family Tuesday and will be gone 9 days. I hope this problem is resolved when I get back or I am going to ask for credits, credits and credits as I have several problems in 2 parts and the shows on the premiums I have recorded I had to delete as I want to watch the whole show. Have a Happy Thanksgiving everyone.
