well the region code doesnt have to do anything with film lenght, i suggest bringing the region code in the line with the production company
and I agree that we don't need a header if there's a menu item there anyway
regarding DVD info, I think there should be a line for Extras too. the subtitles line should (if applicable) note if there's forced subtitles in whole (like with some french dvds) or in part (with restored scenes).
the word "uncut" is a bit problematic. for example, while GBU is certainly not "cut", it's not "uncut" either, because there's things missing. we should add a "cut" to it if there's a longer version available, though
with picture it should say either 16:9 or anamorphic, as it basically means the same, i.e. enhanced for widescreen televisions
