Query: Great film but problem dvd

I love this DVD but there must be something wrong with the latest batch of DVDs because the motion is very jerky and nobody else has complained about it (yet?). I tried playing it on two different computers, my DVD player, and my XBox, so I know it is indeed the DVD. Amazon replaced it after I explained the problem, but they just sent me another bad DVD. So it's actually a disk-maker's problem and Amazon doesn't seem to have a way to deal with a situation like this. I would very much like to share this movie but it's very hard to watch. If I were the publisher of this DVD, I would be very quick to fix a problem like this.
