after looking at the region 2 (uk) version of the 3 disc set on www.play.com and then looking at the region 1 (usa) version on www.playusa.com it seems there is a difference in the running time.
REGION 1 = 15hours 42mins
REGION 2 = 14hours 39mins
this doesn't look good for us here in the uk with region 2 because it appears the orignial episodes with 1-2 minutes extra from the original NBC network version will not be included.
the only option is to wait an extra month for the region 1 set to come out with everything on it. does anyone have any further info on if this is correct.
