Wasn't sure where to post this so hope it's ok here? Ok, got my sky+ to go into my yamaha 750 amp using s-video,also got my pioneer 575 going component in to yam. Got component out going to my AE700,when i switch it to tv on the amp it's blank.What settings should the sky menu be on.Tried RGB and PAL but still no picture. Getting a picture ok when amps set to DVD. Just thought i would be able to use the component switching with the sky box? cheers.
