Sometimes our sky+ box (not sure what it is, what ever Currys did for £199 in Jan) goes out of sync. Is this a common fault and is there a fix? turning of and on seems to do it, but it's a pain. Sky+ -video to Plasma through scart -Audio to B*se 3-2-1 via optical (did it analogue too) Speach seems to come out BEFORE image! ....... are all Sky engineers wers?
