Its on double sided discs, yep, the dreaded DVD-18s. My disc 2, i forget what side, wont play all the way through now. But when i first bought it it played. The outer edge of that disc has a purple color now. It didnt have that when i bought it. DVD-18s are the devil , and i belive the high defect rate of some of those Universal shows are why they had low sales on DVD. I know i had to return more than one Universal show on those discs, cause they wouldnt play all the way, when the disc was new! It only took 2 or 3 years for Adam-12 to start to "rot".
