I've got my Sony DVD player connected via the vcr scart socket on my sky+ box. However, when I watch DVD's they all have a very strong red tint. I've tried a different scart cable. I've even tried a different dvd player. Same results every time. It works find when connected directly to my TV but my tv only has 1 rgb scart socket which sky is connected to. Any idea why this is ? Am i going to have to buy a scart switcher to get round the problem?
