Alien Quadrilogy vs Anthology

[pcp]

Hi All,

I have Quadrilogy and I'm considering buying the newer Anthology set.

From what I know the newer set pretty much has everything the old set has plus a bunch more. But I've also seen it mentioned that the commentary on Alien is not the same (www.dvdbeaver.com/film/dvdcompare2/alien.htm).

Can anyone confirm this?
