Known problem on ALL the Sharp TV since the first Quattron model...

If your receiver does not have an adjustable lip sync delay just like the Integra do, the only way will be to get run all the HDMis to the tv and a Toslink to the receiver...

You can't believe how happy I am to read your thread, As I aleays thought I was the only one complaining about that... Even at Sharp tech support they called me crazy...
