Does anyone else do this? I've just noticed a few instances where I have multiple editions of a movie, each on one disc that take up more space on my shelf (eg Fist of Legend - theatrical cut and extended version).
So I decided to make my own 'combo' by taking out the cover art for the theatrical version, putting in a 2 disc DVD case with both the theatrical and extended discs.
I'm going to try it with Enemy of the State - theatrical (BD) and Extended (DVD) as well (sadly there's no BD release for the Extended version)

I thought it would be a good way to save space

The only thing is it kind of mucks up numbers on my colllection database, as now I dont know whether my home made pack counts as 1 or 2 items.
