Replying to Faulty blueprints?

i just got blueprints in the mail yesterday, and i was so excited to watch it in my dvd player. When i turned it on and pressed play it said something like disk error check disk. i didnt want to fuck around too much, i just wanted to see the vid, so i tried again, but then when it didnt work i tried my x box. it plays in the x box but it also tends to skip a lot. Did anything like this happen to anybody else? will i be refunded or get another copy if i send it back even though it was opened?
