This happens more with my CDs than DVDs because I'll play them in the car and put the disc "temporarily" in another CD case because I had taken the original case in the house. Every now and then I'll have a CD case opening party. As for DVDs, I just re-ordered the Universal's Hammer Horror Series because I'm missing one of the DVDs and I'll kick myself if I don't replace it before that title goes OOP. I should find it for sure now.

I'm missing a stack. Since I've moved twice and organized everything in between moves they're just plain gone. I'm voting they were stolen.

I have to retract my last post (#27). Recently, I wanted to watch Office Space which I know I've had since I started collecting but haven't watched in years, but couldn't find it on my shelf. I loan movies out regularly, but I usually keep a good tab on them. Looks like I'll be re-buying this someday.

I had this happen once, with The Office sets somewhat coincidentally, posted that they were lost on my Facebook page and had them back the next day.

I recently moved and my library is all over the place, we wanted to watch Goodfellas, I looked for over an hour and looked multiple times after that and still have not found it.

I'm also missing disc 1 of Jay and Silent Bob Strike Back and the disc to Dumb and Dumber.

An easy fix as I'm able to upgrade all to blu-ray.
