I have the same issue, locked 7 times in first 10 days. Pissed, re-upped for 2 years to get it (and a $40 1 year credit). My (seemingly highly competent) tech support supervisor said it was likely caused by the internet connection to the box (I use a homeplug AV modem, curious if that might be the issue). He said a fix could be over 6 months away which was freakishly honest. I have unplugged the ethernet cable (not a big deal, can plug back if I want a ppv, don't use on demand) to test that theory. I asked for a $50 one time credit which was readily agreed to so I obviously should have asked for more.....Hate that. I will give it a month then ask to roll back the commitment and get my old DVR back.
