Help! Compatibility issues with standalone DVD players

Hey,
I’ve waisted so many blank dvd’s and so much money already i’d be better off buying the movies…I tried using the demo version of nero 6.6.0.8, dvd shrink, alcohol 120%…I download the movies off a torrent in .VOB format and whenever i burn the dvd it works fine on the computer but never works in a dvd player…Please help me!!
