Two Versions of DVD Season 1

I just got season 1 in the mail today the extended edition. Does anyone else have this one ? When I rented it through Blockbuster online last year, I remember the discs had pictures of the cast on them. I went to TvshowsonDVD.com and it said there is supposed to be a gag-reel and bloopers. That must be on the original discs, although I haven't looked on this DVD set I got which has clear discs.
