Hi there, I've got a Sony AVD-S50 DVD player/amp and KEF 2005 speakers and I'm very happy with the set-up. However, in the last couple of days I've noticed that on a couple of disks (24, American Pie) the audio has been unsynchronised (sometimes slightly, sometimes severely). It's quite distracting and not what I expect from a digital source! Has anyone had a similar problem and is there a solution? Thanks.
