I've said it before, and I'll say it again. A game need to do
three complete uninterrupted lines of VSYNC to work properly
on all TVs. Some games try to use this time to do some other
setup work (Solaris and Desert Falcon are known offenders in
this respect) and this seems to to cause problems on some TVs.
I don't have an electronical explanation for this though. Maybe
one of the harware experts here has?

If your TV still has a vertical hold knob, you might be able
to tune it a little bit to sync your TV to these problematical
games, without messing it up for the normal games.
