I've truly enjoyed my subscription to Cinemax and its huge selection of pick and choose grade Z movies (along with the European and Mexican stuff that runs at 3 in the morning, but what are VCRs for?). So for a few dollars more a month I added Showtime. Well, the first movie I watched all the way through turned up 6 minutes short of the running time, and I recalled reading that Showtime time-comresses films. So can anyone out there tell me if this is so? Does HBO do the same? The big question, then, is, do they also cut stuff to fit the movie into 90 minutes? Carol Slingo
