I know Mark feels. When we moved down to the states, I had to save space so I moved all of my DVDs into big CD wallets and threw out a number of VHS tapes (but put some into storage at my ‘rents).
When we were moving back we decided to sell the DVDs that we weren’t going to watch again and still ended up with three boxes of DVDs.
I don’t think I could part with the cases now though, I like the idea of displaying all of my DVDs on big shelves where we can easily pull them and watch at our leisure. Add to that my 5 disc platter player and you get nice easy viewing of whole DVD sets and so on.
I guess what separates me from Mark is that it was my decision to castrate my collection.
