Hi Panasonic DMR EX85 DVD recorder. I am on my second machine and am still having problems with picture freeze and stutters on TV viewing and TV recording. I have had an error code U80 with total loss of picture / signal. It does seem to me to be signal related as a weak signal is worse, although it still occurs on 10/10 signal strength/quality. Panasonic simply ask to return it to a service centre. Do you know what this error code means?
