Just an FYI for those hoping to play this set on their Blu-Ray player. It won't work. I haven't been able to figure out exactly why yet. It might have something to do with the enormous amount of memory on the audio segment of the disc, but my Sony Blu-Ray will play exactly 23 seconds of both discs and then it stops. It never gets to the menu, just a brief animated graphic of the Infinity logo WITHOUT sound, then it sticks. My player is brand new so the problem isn't with the player. When I put the discs in my regular DVD players they did fine, but there is compatibility problem on Blu-Ray players.
