I know it may cost a little more money but they could add a second disk like they did on the Pirates movies if they want to add more special features.

For people who say uncompressed PCM takes up to much space on a disk look at this. Lost: S3 has 5 eps per disc at about 45 minutes each so 225 minutes (3hrs 45 minutes) of gorgeous video and Uncompressed PCM as well. And Hellboy had 3 Uncompressed PCM tracks.

With the new video codecs like avc, and VC1 companies should put a original audio language PCM track on the disks.

PCM was only a stop gap until the CE's caught up with providing HD audio in their audio line up of products.
Now that just about everyone offers a HD audio receiver, why add a PCM track?
A new receiver would go great with that new blu player!

Exactly. I know we all love PCM soundtracks but it wasn't put on there for us audio enthusiasts. It was put there until more receivers supported TrueHD and DTSHD-MA. PCM is nice but we honestly can get the same sounding audio with less spaced used on the disc.

The truth to this is that as small as the Hi Def media market is, about only a tenth of that market can even take advantage of pcm or truehd or whatever format other then DD 5.1.

EVERYBODY can watch the bonus content although I agree it just fills up space. But you have to spend another $1k to get to pcm 7.1 and that market is VERY small compared to the small hi def market already.

Actually you need to spend that money anyway to get the new lossless codecs anyway....

DTS HD MA sound dawm good IMHO and TrueHD too. Off course i use bitstream to my Receiver so i get the goodies done inside my receiver!

One of my demo disc is actually Shoot'em up...

It's so they can fit more dub tracks in lossless on the disc

Frankly, I say let dublovers eat compression. If they're too lazy to read subtitles, have no problem compromising original intent and are willing to put up with abomidble acting then they deserve their fate

My point is that Average Joe Six Pack will be satisfied with just plain old DD 5.1.

Paying for blu ray makes sense if you have a Hi Def TV and watch movies. If you already have DD 5.1, this would mean replacing something that still works which most people wont do.

Don't get me wrong, I've heard 7.1 and I want it and will get it, but the AJSP won't.

Agreed.

It's only SPHE that appears to be moving away from it. Lionsgate continues to deliver awesome 7.1 PCM tracks and Buena Vista has always been a stalwart. Warner has always been hit or miss (and unfortunately usually miss), though hopefully they'll get more consistent once the shed the HDDUD dead weight and it's handicaps. Wish I had more tracks like the PCM on 300.

That's why I want 75 or 100 gig disks then I think you will see a lot more studios using Uncompressed PCM.

I have a new receiver that will do Dolby Digital True HD and DTS MA they both produce great audio. I have just found PCM to be the greatest of the new audio formats I can hear quite a difference.
