My original 622 reset itself from day one. Usually about every 20-30 minutes, with occasional resets over an hour apart. Today I got a new replacement Vip622 and things are much better! While the new one was problematic in getting the initial setup done, since then all has been good. Running about 4 hours now with no reset. But now a strange occurence, only partial local listings on the satellite locals. Hopefully that will clear up overnight.
