Lag and reboot problems
I really noticed lag was several seconds last night with an RF remote , then again today with another remote. Decided to pull the plug today to do a hard reboot. After about 3 minutes, there was no sign of activity from the 722, so I did it again. This time it showed initial activity, then got stuck for 15 minutes with no progress made, so I had to it again! During the 3rd attempt I called Dish support to complain. It did succeed the 3rd time, but took over 20 minutes to boot and download the program guide. At least for now, it is responding better to the living room remote.
Note: I have discovered from past experience that calling support is usually effective at getting the 722 to work--not because they tell me to do anything that I haven't done already, but because the 722 somehow knows I am calling tech support and wants to make me look bad.
