You guys going on about the TL-51 deal....they aren't going to release a disk that doesn't work on 1st or 2nd gen players. That's why they are bothering to go through the DVD forum.
On the BD side however, you already have discs like POTC that take 1.5 to 2 minutes to load...you don't think situations like that might become more commonplace with 1.1/2.0 discs on 1.0 machines? It's something I worry about.
I can tell you this....I may not watch the extras and commentary very often, but if I want to, I want to be able to. Stop making excuses for Blu-ray's incomplete rushed-to-market specs. BD should have required "final profile" from day one. Not to mention requiring the players to decode lossless audio formats. Inexcusable IMO, and one of the major reasons I'm holding out for a properly featured 3rd gen/DF player.
