Why don't you try this little story on the folks at Sound & Vision? They
certainly requested an encoder from you and got none. You are the one who said
"the MOST IMPORTANT test... the comparison of each soundtrack, directly to the
master that it was encoded from," yet you prevented them from doing it.

That is the choice of the manufacturer. Maybe most of them believe it's a non-
issue (as do we). Those who don't are quite able to avoid it, and they do. In
any case, it's not a coder issue.

Because if what you say about DTS gain being 0dB is true, then I have no way
to reconcile your unsubstantiated claim that Dolby tracks play back 5 dB
lower unless it is because you are deliberately inflating the number to try
to reach the "almost one bit" figure you quote. The dialnorm value imposes
4dB attn in most movies, and we make this fact well known. Where did you come
up with 5dB? Did you measure it? Against the master or against the DTS
version? If you agree it is a mistake, then why not fix your Q&A?

Really? How so? Maybe by DTS's definition of creating an LFE track while
mastering, but not by ours. Sorry, you are wrong. This should be corrected
also in your Q&A.

Then that's the master the Dolby Digital processor delivers intact. It is now
quite humorous to see YOU, of all people, arguing that the coding system
should be blamed for what the mastering people choose to do. And by the way,
this process (if and when it is done at all) is not to alter what the 5.1
listener hears, only what the 2-ch downmix sounds like. In fact, if there was
some concern that the 5.1 track was being aesthetically altered (which can
mean certain dismemberment in Hollywood), they would just use a separate 2-ch
mix.

Yes, as I succinctly illustrated.

It was DTS's own licensees that came TO US with stories of Chapter 11 and the
like. These didn't originate here. And guess what? Your own investors called
twice trying to sell us DTS, lock, stock, and barrel. Seems they want to
recoup their investment before it's all gone. We're not the only ones they
called, either. No takers yet, I guess.

DTS has been so belligerent and foul that we finally had to stand our ground
and respond to the baseless charges and unrelenting hype to set the record
straight. The piles of garbage that DTS has poured out over the years has
been truly amazing. Beard, Neighbors, Slusser, and now you, Mr. DelGrosso,
have done more to sully your own reputation than we ever could.
And if you think we are the instigators, didn't you notice how quiet it was
around here until you signed on again after your absence and started right in
with more misinformation? As long as you persist, we'll be there to correct
you. Don't let us all down by actually fulfilling your promises to leave the
NewsGroups. It's all so entertaining.
