Never mind 1080i what about 576i (ignoring TVOUT chips which seem basically
broken in this respect) ?!?!

It seems the simple problem is that FRAME sync (rather than FIELD sync) just
isn't working
somewhere along the line...

We shouldn't need to deinterlace if we have an interlaced display (capable
of the relevant resolution) available, full stop, period, end of story.

The fact that we do means that the syncing system is not working
somewhere along the line, maybe it's the card, maybe the nvidia driver,
maybe Myth ... does anyone know?

Regarding bob deinterlace and "too small a refresh rate". There was a patch
posted on the list a few weeks ago by a guy called Viktor. Works well.

Cheers
