A singls screwed disc, or calling it it's more technologially correct term, a faulty disc

, is a rarity. Maybe the actual disc itself has been damaged in some way. I have a PC Gamer DVD that dosn't read properly as it is slightly bent

.
Or even the whole batch of discs are at fault, and that has happened before.
So with that in mind lets continue.....
.....sam_i, the problem will probably be with the batch of discs bought by the place you bought it in. Go the there and ask them if it would be possible to play the disc, just to make absolutely sure it dosn't work. If it does then it MAY actually be your player, but only with that disc.
If it dosn't work in the shop; the only two alternatives would be asking for your money back, or more realistically the shop will ask you to pick another one.
I REALLY hope you get it sorted out and enjoy what is a hilarious movie in crystal clear vision.
