I rented the Adam-12 series disc 4 from Netflix, the dvd mail-order rental service. I had read earlier that the Adam-12 dvds put out by Universal Studios were double-sided, so I thought I'd be getting the same thing, so imagine my surprise when what arrived in my mailbox was a single-sided dvd with professional-looking disc art that said Adam-12 Season 1; Disc 4; with Universal logo and copywright information. I had no idea that Universal was putting out 2 different versions of their TV series: single-sided and double-sided discs. I know a lot of consumers wish Universal would only used single-sided discs--especially with all the troubles the double-sided discs have with skipping and freezing. Do they only do this for rental stores? Did anybody else know this?
