I have been having the same problem as Archaon....I've been on the phone with 4 different Sony Reps, who couldn't resolve the issue either. Their final response was to send the unit to Texas so Sony could install the firmware themselves. However, that would take approx 4 weeks... Any help here would be GREATLY appreciated OOOPS, I just read Stuge's last post and installed the 201 version , and it worked!! Thanks Alot. Someone should notify SONY about this so others don't spend as much time as I did trying to tweak the upgrade. Thanks Again!!
