Bandwidth, more than storage capacity is probably what's keeping lossless audio off of HD DVD discs....

... not to mention discouragin the use of PIP, seamless branching, better video bitrates etc.

For some reason, no one pays much attention to bandwidth limitations but I suspect this is the biggest reason, HD DVD movie releases tend not to include lossless/uncompressed audio.

While bandwidth limitations would certainly have an impact on unusually long features on single disc HD unless the inevitable multi-layer presentations come to pass, the "lossless/uncompressed" algorithm issues are more rumour and cheer-leading hyperbole than fact based. Have you personally ever heard any subjective difference in sound quality between the same titles offered in both formats?

BTW, have you had a chance to try out that 3x1 HDMI switcher? I upgraded to an Oppo switcher about a month ago so I don't need the loaner back, but if you don't want it a couple of folks at the meeting elicited an interest.
- Here's a primer on the subject from High Def Digest (Open in New Window)
- That article doesn't discuss bandwidth limitations, it's PCM vs. lossless codecs.... - oscar 14:45:25 12/10/07 (0)
  ...being discussed. And I've disagreed with Zyber before...
  
  There's always been a very obvious subjective difference between lossy and lossless with the same movie on my system, but than again the vast majority of lossy is no better than 640k DD+). I don't have any "high lossy" (1.5mbs DD+) vs. lossless soundtracks on the same movie to compare to (yet).
  
  "Transformers" provides one of the best soundmixes I've heard (minus the LFE which I've had issues with on the LG) but I still don't think it matches the clarity, separation, and dynamic peaks of some movies I have with lossless or uncompressed PCM soundtracks... YMMV.
