Aspect Ratio question - encoding in TMPGEnc

[thetoof]

This may be very noobish... but I didn't find any good answer.

I've got a 640x480 movie that I want to encode to DVD, so I resized it to 720x480.

My question is, once that's done, which of the following options should I choose?? (and what are the differences between them)

4:3 525 line (NTSC)
4:3 525 line (NTSC, 704x480)
4:3 Display

Hi!

You should choose to make your life simple and, in TMPGEnc, load the "NTSC DVD" template...

Well, that's what I did... but for some reason, when I load my avs in TMPGEnc, it automatically selects 4:3 525 line (NTSC, 704x480), even if I resized it at 720x480, so I was wondering if it would be more appropriate to use one of the two other settings. That's why I asked what are the differences between them (their effect on the encoding process).

There's no problem in using the 704x480 setting...
