I guess G33 doesn't have 2D video overlay and always uses textured
overlay?

Interlaced mode support is not a real problem here, I have a patch
which generally works (though may need some additional, probably
trivial work, and I tested only PAL 576i).

The problem is the lack of frame synchronization between the program
(X client) and the Xserver/hardware.

Is it now possible to have frame synchronization, using textured Xv?
I mean, Xserver switching active video frames on vertical retrace
or something like that.

Right.
