Audio out of sync with video DVD

I just bough my first surround processor, a Rotel 1065. I Do sound mixing and editing in the movie biz so I might be more sensitive to this than others but hope there is a fix.

I notice when watching a DVD and listening though the Rotel the sound is not in sync with the video? It seems to me Rotel would put a video delay in the signal path to compensate for this, but it seem they do not.

Is there a fix for this?

It could be my Cheep DVD player.

Thanks, Mark
