Query: does not work on a regular dvd

i bought this movie twice from different sellers and i tried playing it on five different dvd players and it did not work at all so i returned it and got another copy and same thing happened..it kept saying error or mixed media disc i thought it was the region but it says its region one, so i have no idea why it doesn't work and i don't know how many more copies are defective.so don't buy this at all there has to be a problem with the dvd or something!!
