I have had 4 922's that will not record. The unit will record for one or two minutes, then it will lock up and has to be reset. This happens when the unit is off tries to record a show. The front panel will have the green light on, but you can get the menu and the dvr list up on the screen but no live tv without reboot. We have tried different outlets, switched the port on the switch nothing helps. The dish techs are telling me that there is nothing that they can do. They say everything checks out as far as the install goes. I had the first unit for 4 months and this just started all at once.
