Yes, I thought that too. I just wondered whether the other option I had
to turn on (is it OpenGL sync or something .. on the same page) had
cause the grey OSD instead.

Right, thanks. That was another thing that confused me as I had the
flickery grey OSD with various different deinterlacing methods.

I have a nVidia 5200 card.
Getting a flicker at the top or bottom of the screen and I think it was
around solid blocks of colour too (eg logos), but that could have been
due to a deinterlacing method I suppose.

That's just reminded me that I did set that up in the past. I just never
think of it with myth because I feel I need to be looking at the results
of whatever changes I make.
Thanks for your help Dylan!
