I have no opinion one way or the other on lossless versus uncompressed. I'd rather they utilize the compression if it allows for higher-quality video. If the format could handle 5 hours of uncompressed video and audio, I'd be all for that, but I wonder how noticeable the difference would actually be. The best stuff on Blu-ray looks and sounds amazing. To see any major improvements will take a new format, and on the audio side, how much better can it actually get?
