Few considerationss...

I come from PAL world (H=576) and not from NTSC world (H=480) and I think there are differences in converting down from H=108 (pal is 1,875:1 ratio NTSC is 2,25:2)

In the article there are at least TWO things I think are wrong.

1st he suggests MPEG2-I while you should use non-compressed codecs (or less compressed like Cineform on PC and Pro-Res on MAC)

2nd. Hollywood DVDs are double layer. That is 8.5 Gbytes and very rarely they use all bandwidth available. Sure they have dedicated softwares.. but bandwidth is not the main reason.
