Dollhouse BD Trouble

[moviemaker928]

Hello. I rented from Netflix Dollhouse season 1. I have the Samsung BD-P1500. I watched the 1st disc, had no trouble with it. I pop in disc 2, it loads like disc 1 did, I go to play all, it just repeats the menu over and over. I go to play a single episode, I click on the episode and it loads like it's about to play the episode and then stays on black, the numbers on the player are all at 0, nothing is happening, I press stop it stops, so it hasn't frozen. I put in disc 3 and the same problem happens however when I go to special features it will play the supplemental material as well as the un-aired pilot. I last updated the firmware on April 18 2009 and I believe that was 2.4. I went on samsung's website and there is no firmware update so it can't be the firmware, do you suppose that discs 2 and 3 are just bad? Thank you.
