Hi, First rule: You cannot

Hi,

First rule:

You cannot produce more quality than the original quality in hand but some software can push on maximum image quality. and maximum bit rate allowed.

Rule 2

SD is 4:3 ratio HD is 16:9 ratio you need to crop your movie screen some software like Sothink from Sourtec can do the work.

Nobody can obtain the B-R quality 720 x 480 is far than 1920 x 1080 but not to far 1280 x 720.

You can save your DVD try with demo before to invest in costly software mathematic is mathematic.

Regards,
