Well, my firmware upgrade scores 99%. Things seem to work fine unless I tune to channel 199 (TCM). It occurs to me that is what happened at 2:00 pm. I haven't found any other channel that causes the system to report it is upgrading firmware and go crazy in the process. For now, I have deleted 199 from my lineup. I don't want to miss the Euro 2008 finals on Sunday so I don't know if I should try and fix things until Monday when there is likely to be less of a wait if Cox has to roll a truck.
