I broke my ps2 - Disc error

[Danked]

The only problems I've had with my ps2 is that my first volume of Cowboy Bebop doesn't play with the DVD player. I keep getting a disc read error. I don't know why this is because it works in all my other players and all other DVDs have worked in my ps2 so far. I'm supposed to be getting the rest of the volumes sometime this week in the mail so I'll see if it's something specific to the series of DVDs, but I hope not. I want to be able to sit comfortably on my couch to watch them, not at my computer. :-(
