No problems on my 722. I switched to dish from cablevision a few years back though, and if you want to see a sluggish receiver, cablevision takes the cake. That was actually one of the main reasons I switched. Surfing around with their equipment was unbearable.
Yeah, even with the bouts of sluggishness my 722K has at times, I would never go back to Insight's DVR. That thing just didn't respond period. My 722K is light years ahead of that Motorola DVR.
