I have some avi files that I've converted to DVD using avi2dvd (I think). I put them in the DVD-ROM in my computer and they play fine, but when I put them in a DVD player it says something like "format doesn't match tv system." I'm assuming this is because the program is converting it to a PAL version. My question is, is this why it's doing this (b'c of PAL) and what programs do ya'll use to convert?
