I want to try out (which is probably a bad thing since I'll probably buy them all) the Doctor Who DVD sets. What are some of the better releases. I'm not talking on a story level since I'm pretty familiar with the good doctor, but on the level of Extras Picture quality etc... Also are the Disks the original 30 min episodes? I know probably alot of Whofans like the shows when editted to gether into their "Movie" Versions, but I always thought the good doctor worked better in their Serialized format. I appreciate the input of Whofans out there.
