I've had my HR20 installed last Tuesday. Had three or more lock ups the first day during the setup. Recieved the software upgrade on Wednesday and continued to have lockups. Talked to someone in tech support and they walked me through all the steps, the red button resets, the disconnecting the power cord and switching the two cables, etc. He finally determined that the box had a problem. Recieved the new HR20 this morning. I hooked it up and I've had four lockup today. Three of them were while I was setting up my wishlist and basically going through the setup menu's. The most recent one is the strangest yet. I was recording a show and at the same time flipping back and forth between live channels. The picture went black but the banners would show up. Finally had to hit the red reset button again. This is getting old. One week, two new boxes and a dozen lock ups. Before the HR20 was installed I read all the reviews but didn't think it could possibly be that bad, but I'm living proof that something is going on with my box and It's starting to get old, fast. My HR10-250 never locked up. I couldn't wait to get my HD local and now that I have them I'm wondeing if it was worth it. Is anyone else dealing with this same crap. Could a new software upgrade possibly fix the lockups? Thx.
