Geia sou Ellada!
I had the same problem with my vcr and my dreamcast...
I found that the 'scart input' signal is only displayed on the tv when the video is on 'off' or rather 'standby' mode.
Just make sure your tv is tuned to the AV channel you normally watch your vcron, then press the power button on your vcr to switch it off and your amiga should now show...
If it doesn't ....well animagic was right....
It took the best part of an hour of cursing (using all the Greek m* words) before I realised! :-)
Good luck ....kai ta leme
