So figure 2.7 hours with sound, on a 100gig Blu-ray DVD. I'd be happy with that. At least there wouldn't be any compression artifacts.

Did you not read what I wrote? You can't play the lossless codec off a Blu-ray disk for one major reason: BIT RATE. The mechanics inside a diskdrive can only access so much information per second. Huffyuv uses a 38 megabytes per second bit-rate. That's a hefty amount of data. Bluray can only access 4.5 Megabytes per second. It is thus IMPOSSIBLE to play that strong of a codec off of a relatively slow medium.

This is why you need compression. Compression isn't necessarily a bad thing when it's done right. The new compression schemes they'll be using for the new HD content is amazing. I agree with you that MPEG-2 sucks, but when you want digital quality picture, you have to make some compromises.
