Just setup a Sony DAV-S550 and I attached it to a pace sky+ box and when viewing recorded items from the Hard Drive the sound is out of sync with what you are watching, more obvious when people are talking etc..., the timing is out milliseconds (i didnt notice but er indoors did watching pop idol) quite annoying (the sound not pop idol ) , anyone else had this. Watching normal "live" sky is fine. Would optical be any better? It must be to do with the hard drive, does sound come off the disk quicker than the video? or vice versa? ? Ive connected using phonos from the back of the sky+ into the amp, Cheers Buzz..
