Well, I got them today, & so far, they all work!!! They play in my dvd player, & the signal, audio, etc. is all perfect! Go figure! I originally tried one in my dad's dvd player, & it ran, but the signal was all jacked up, but, it all works fine on mine. I was playing around with my dvd player a week ago, to try to figure out a code to make it regionless(since, on my particular model, I never could find a code, some sites even said there was none known for mine). Anyways, I guess this thread ended up useless, but, I appreciate all the effort people put into trying to help me. Still, I'll probably make backup's, & do the region change, etc. on them, so, I guess this thread will come in handy
