Nice to see other people as nutty as I am with movies - I have over 1,000 VHS tapes, and I believe I'm getting close to 400-500 DVD's. I use to keep track of them all in an excel spreedsheet, but I don't have the time for that anymore.

Duplicate movies - I just got my 3rd copy of Karate Kid! (First copy on VHS, got DVD normal edition awhile back, and just recently bought the DVD box set with all 4 karate kid movies in it.)

Have a couple of Clerks DVD's (Original and 10th anniversery edition), plus a couple of Pearl Harbor DVD's (Original & 4-disc directors cut.)
