I just go the It's A Mad Mad Mad Mad World blu-ray and it's great. The quality is amazing. But I came across something funny. The movie plays fine, as do the trailers. But when I tried to play the extra feature, Something A Little Less Serious, the player stopped the disc. I thought this was odd, so I tried a few more times. Every time, the player, while not shutting off, just stopped playing the disc. I tried the blu-ray on my computer and I did have to update the program that I use to watch blu-rays. But it worked fine on my computer. I don't see what's so complicated about the disc that I'd have to update to play that one specific feature, but it's not a big deal. Like I said, I can always watch that feature on my computer, annoying though it is.
