After several months of intermittent problems and troubleshooting, I finally called and asked for a new box be sent. CSR tried a little to talk me out of it, etc, but I insisted and even didn't argue when they said it would cost the 20 bux s and H. The new HR20-700 arrived in only two days. Set up and activation went off without a hitch as well as the 168 update. It' s been two weeks and the unit is rock solid. Better than ever, and it's now such a pleasure to not have to worry if a program is going to reccord with dropouts and other issues. The carton was marked with a manu date of Feb 07 - compared to the 9/06 of the original unit. Maybe there are fewer hardware issues with newer units? I know others have gone through several swaps with less success - but maybe things really are getting better.
