MGM Midnite Movies is a series of horror and exploitation films published usually in double feature format with two films on one disc. Usually the two films share a similar theme (attack from another planet, bikers, gorillas...). First on the list are all the double features of the series. Most of them have also been published separately as single features but I didn't find it necessary to inform which. The point of the list is more to inform which films belong to the series than to give a full list of all the dvds.
After those come the titles which have not been published in the doublefeature format and after them six MGM box sets which mostly include the films listed before. Some of the titles (and 3 of the box sets) on the list have been long out of print. The MGM midnite movie series has been going on from 2001. Last there's the only-on-vhs films.
