Hi, Sorry if this is in the wrong forum, I was told this was a good place to come for AV stuff. I've got a problem and I was hoping somebody could help. My TV keeps jumping from 4:3 to "Full" (Which is essentially 16:9 on my TV I think) and then back again and it's driving me nuts. It used to be that it would only do that when I was watching DVDs which were 4:3 on my DVD player, like Futurama and stuff like that. I recently bought an AV switch and now it's doing it with my Xbox AND my DVD, but not my PS2. It's really odd, it just keeps jumping from one screen size to the other at around 3 second intervals. If the picture is 16:3 (Or widescreen or whatever) then it's ok, but if it's 4:3 then it goes mental. Even if I manualy change and lock it to 4:3 it just does it again straight away. Oh yeah, it doesn't do it with my Sky digibox, and never has. Does anybody know what this could be? The way everything is connected is: DVD Player, PS2, Xbox, Skybox all running through an automated switch into my TV. I've tried changing the AV switch to manual and that doesn't work either.
