Friends, 10 Season set now on Blu-Ray!
Friends DVD Set!
Joey, season 1 (from Amazon US) and season 2 (from Amazon UK -- This is region 2, it won't play in a typical US DVD Player!)
By the way, it's been pointed out that these "region 1" DVD releases are also coded for regions 2, 3, and 4. While it's true that the region codes on the disks do show 1 - 4, the disks also have RCE protection, which could very well prevent the disks from playing on DVD players set to regions 2 - 4. So if you are not in region 1, buy these at your own risk!
