Anybody else having this issue where the OSD shows up for the timeout period (mine is set to 5 seconds) quite frequently during a DVD movie?

I watched some of the Cars DVD yesterday and it was appearing approximately every 60 seconds for quite a while. My TV is connected via an S-Video cable from the 1070.

I *think* this behaviour is new since applying the 'no-audio fix' a few months back. I haven't had a 'no-audio' incident since applying the fix but this ODS problem is becoming annoying...
