I want to convert an avi with 25 fps to SVCD. I will be playing this on my DVD player which is hooked up to a NTSC TV. Do I need to encode the entire SVCD as PAL with the 480x576 size, or is it sufficient to encode as a 480x480 NTSC SVCD with 25 fps?

Edited to add: I did a whole bunch of trial clips using PAL SVCD standards (including the 480x576 size) on my TV with different settings for the source aspect ratio to test for overscan. None of the clips played back normal--there was green pixelation and the aspect ratio was distorted. What's the simplest way to do this? I don't want to do a framerate conversion because my DVD player can handle PAL, but I'm just not sure what I should do.
