I mean, I've my source at 720x480, without any black borders on the side, but somewhere I've read that the 8 pixels at the right/left were not used, so I always crop 8 pixels at x and 8 pixels at -x, and it ends being 704x480.
Is it true? If so, why?

No, it isn't. You only crop if the picture has black borders on the side. If it doesn't, then of course leaving the full 720x480 is the way to go.
The whole "8 pixels at the right/left are not used" thing only applies when they're not really used (aka, when the picture has black borders on the side).
To sum it up, some DVDs use 704 pixels (has black borders) and some use the full 720 pixels (doesn't have black borders). You can tell just by looking.
