It seems with this Onkyo TX-SR805 I notice some A/V sync problems on different sources. It's fixable with the Sync Delay option. However I'm always second guessing myself on whether or not it's as perfect as it's going to get.

Any good techniques or a specific part in a movie? Maybe a special DVD you can purchase that assists with this? Watching lips is hard to tell.
