this seemed very bizarre to me and was wondering if anyone had an answer to it. i began burning dvdr's with dvddcypter and then used dvdtoolbox. thos discs i could not get to work in my xbox, my 2 samsung dvd players. it only worked in my sony dvd player. now today i used only dvdshink. i clicked on all regions and burned the disc, both a dvd +rw and a dvd +r/w and both worked in all my dvd players. does anyone know why? thanks for the help
