The only real problem I'm experiencing with my new ViP612 is an occasional frame jump, both audio and video. Sometimes it's like a freeze but usually it stops on a frame and starts jumping a few frames foward and keeps doing it. When I skip or rewind back it usually will run smoothly although on occasion I'll simply end up missing a few seconds of a show. I only watch recorded programming. And I am mostly watching while other shows are recording. I'm hoping its not hardware, but it could be hardware or software. I'm beginning to wonder if the 612 either lacks sufficient cache size or simply uses slower memory or a slower processor. I've noticed that the 612 takes longer than the 722 to move shows to and from my EHD. Also, the 612 "feels" different from my 722 in terms of remote response lag. Any thoughts on this would be appreciated. Also, is there any web info on the hardware used in the ViP612?
