Thanks for the tips regarding Trigun guys, but like I previously mentioned; it played the first sixteen and a half episodes just fine. I'm pretty sure that it's a defective disc. I've only experienced this once before, and that was on a used Stratos 4 disc. Same deal, only one (or two) episode(s) in particular had an issue. The screen starts gettting these little squares at first. It kinda looks like something from an Atari 2600 game; then it starts to lock up, and I have to turn off my DVD player. Irregardless of the problem, the solution will arrive in the mail in about 3 weeks. As far as attempting to resell the Trigun set, my personal code of anime chivalry and ethics prevents me from spreading my misfortune to anyone else (kidding). I guess I'm not really. Sure, I could get a little money back; but I would feel too guilty for it to be worth it. C`est la vie.
No matter where you go, there you are.
