Hi I have had a panasonic DMRE85H uk version for about a year now and have had no problem but just recently i cant dub to dvd the unit starts to dub but then reboots. It will display self check then go blank self check again it will do this about 7 - 8 times before it will actually stay on and behave again. This also happens on occasion when i switch from dvd to hdd and vice versa and once when i just switched the unit on. I dont know what to do. Could it be the hard drive? i have formatted the hdd thinking it may have corrupted files but no change. do the units have 1yr or 3yr warranty on them? i cant exactly remember what month last yr i bought it. Ive heard of a firmware upgrade but it seems to be for the us version is there a uk version? and would it make a difference?
