Query: technical problems prevent viewing

I wouldn't know if this is a good movie or not because I tried 3 different DVD's and none worked. I checked other slots on the DVD player, checked for dirt, damage, made sure other DVD's worked - nothing solved the problem. I eventually just asked for a refund.I don't know what the technology is for this DVD but it doesn't seem to work.
