I've had a 922 for about 2 years now. I use the sling feature sometimes. Would like the hopper feature too, so I decided to go with the new hopper with sling Did not have much trouble with the 922. It seems to take several times of rebooting from a reset before it works, but other than that and a few lost recordings along the way, it has worked pretty well. From searching the forums it looks like I will have to manually setup the timers on the new box. I am hoping to transfer all my recordings from EHD to the new box though. Install is scheduled for Monday.
