I have a standard 750, that has been setup for 2 years, but from what I remember and understand:
PAL played as PAL
NTSC either converted to PAL, or played as NTSC.
If your TV can handle NTSC then do this as the conversion can cause loss in quality (I think!).
So set the TV type output in the SETUP menu to AUTOMATIC i.e. not PAL or NTSC.
Hope that helps...
