Only if they are trying to use a PAL DVD Player. AFAIK there is no NTSC nor PAL aspect to DVD disks.

The site I used to look up the 'PAL' acronym, because I couldn't remember it, was referring to PAL format DVD's...

Clark is incorrect. There IS a BIG difference between PAL and NTSC on DVD.

DVD Video is MPEG-2, stored a 24 fps.

That's 720x480 pixels, displayed at 29.97 fps, on NTSC (~3.5 Mbps).

And 720x576 pixels, displayed at 25 fps, on PAL.


DVD Audio is MPEG-1, Layer 2 (not mp3!). It's mastered as Dolby Digital for NTSC, and MPEG for PAL.


FWIW,
