converting 1920x1080 to 720x480, it causes 83% video quality loss.
so if convert 720x480 to 1920x1080, then convert it back to 720x480, the total video quality would lose 10% to 20%. any video scaling would only make
original video quality worse, it can not be better.
dvd format is 30i(60i), 30p, 25i(50i), 25p, if converting dvd to blu-ray, it gets 60p, 30p or 50p, 25p. to fit blu-ray standards, it should be 30i(60i) or 25i(50i). however if even field and odd fied not well processeed on dvd, then converting to 1920x1080 30i(60i) or 25i(50i) would make video terrible unless using 60p and 50p, however, the blu-ray standards can't support 60p and 50p.

Wow, lot of misinformation here. You need to read up a little more on what you are talking about.
