Is there a known problem with Lost Season 4? I put the first disc in, and at first it won't boot up. I don't think anything of it at first since I have had other discs not boot up on the first attempt. I take the disc out and replace it, and it does boot up the second time. I watch the first episode with no problems. Then I get to the second episode, and it is constantly freezing at the exact same spot. I try to fast forward or use chapter skips, and it won't play at all after that specific point. Do I have a bum disc? It is brand new, and I looked at it and it looks in perfect condition with no scratches, smudges, or dirt.
