: Have you tried a reboot of the box?
Many thanks all, done the reboot no effect.
Tired the 630 receiver on 3 different HD TVís and no change, my 800 receiver does not have the issue.
Guess Iíll have to wait until they do the next firmware up date for the 600 series.
There is no doubt that the last firmware update changed the way TCM HD displays only in 4:3 even if itís 16:9 movie in HD.
