Hitch - a scratched DVD

So i just finished watching the first 3/4 of Hitch - and the DVD is too dirty to continue playing. I son't mean dirty in the porno kind of way, but dirty in the damaged disc can't see the movie kind of way. Needless to say I'm pissed, and i know the movie store will try and give me a new copy of the movie - Great - as long as it plays all the way through. And what about the other 3 /5 movies i've rented there recently that didn't play all the way through. It's great that they offer to let you see another copy of the movie - but really is that enough? What about a free nother rental.

Look at me using words that don't even exist like nother.

Was really enjoying Hitch too.. funny stuff - some great physical comedy. Maybe i'll get to see it nother night.
