Just purchased a Yamaha DVD S550. It's a DVD player that plays burnt DivX files. I'm new to this, how would I go about making a movie on a cd that is playable. I'd be using toast, I'm just curious as to what format? Mac & PC, ISO 9660? Anyone who knows, fill me in. Also, if I am going to throw a bunch of Divx movies onto a DVD, what format would I do that in? Thanks!
