here over in the U.K. we get the series released in 2 parts for some reason, anyway series 2 part 1 containing the first 12 episodes.here are the extras:
cast & crew feature 37 minutes,
set walk through with series forensic advisor,
producer,director and cast member commentries on 3 episodes,
trailers,
behind the scenes of C.S.I music/special effects/make up.
as usual i believe they are in stunning full-screen.
the set is due to be released on 28th july for around £40.
When i read on this site if people should get an all-region player i would say yes.most of my dvds are region 1 but there are some things we get earlier and perhaps better,imho.

is it in the OAR? (16:9)

This is the same set that was released in Canad last year

I think this is season 2 he is talking about.

Here's Season Two: Part 1

looks like anamorphic widescreen to me. Hope this gets released as such for the eventual Region 1 release.

Season 2 region 1 will be 16:9

Great news! Thanks for the info Martin as I just got Season 1 in the mail today.
