So I've got one of these

Which I use to play some CPS 2 games like Aliens vs Predator etc...

It works a treat but when I have tried two seperate Pandora boxes, neither of them have been able to sync.

Any thoughts? The VGA out works but my TV doesn't have VGA in.

If I fiddle with the video converter I can sometimes see it attempting to sync for a brief second but no go...

Incompatibility or what?
