I assume you want to burn anime (maybe other movie) in NTSC format ? Maybe I'm wrong but I faced the same problem. Most of the time the subtitle is expanded & causing problem to read it. I cannot figure out yet but I think the setting at DVD player or TV need to change into NTSC (format).

704 x 480 ? Not sure. Previously, you burn as 740 x 480. You just change the H (horizontal) pixel but remain unchange on V (vertical) pixel.

Maybe you can try & give the result here.

You should buy DVD-rewritable for experimenting. Mine have couple blank RW for testing purpose.
