   Well, I am sure others will point you to examples. Although the
discussions are about NTSC, I am sure two threads might shed light on
your dilemna:

scea.yaroze.programming     
 Interlaced programming assistance
(thread started by Charles Henrich)

scea.yaroze.programming.2d_graphics
High-res?
(thread started by Clint Kelly)
While checking, I see this thread is also present in your SCEE group.

   It sounds like your program is not finishing drawing in one Vsync.
I am probably totallly wrong, and if you already read those threads,
ooops.
