I have DVD's which were in 5.1 (6 channels), but Dolby
Digital and lossy.

That is very common, but they could also be DTS or PCM.

Is it true that the Blu-ray, now in
7.1 DTS (and offering 8 channels), is lossless on all
channels?

Like DVD Blu Ray is producer's choice, but there are more choices:

http://en.wikipedia.org/wiki/Blu-ray_Disc

"For audio, BD-ROM players are required to support Dolby Digital (AC-3),
DTS, and linear PCM. Players may optionally support Dolby Digital Plus and
DTS-HD High Resolution Audio as well as lossless formats Dolby TrueHD and
DTS-HD Master Audio.[95] BD-ROM titles must use one of the mandatory schemes
for the primary soundtrack. A secondary audiotrack, if present, may use any
of the mandatory or optional codecs."

One other thing, although I have a DVD player with 6
channel output, I also used to use a program called "DVD
audio extractor" to separate each channel into a separate
.wav file. Is there anything that will do this for
Blu-ray? My current Blu-ray player does not offer the 8
channel output.

Your first trick is breaking the content management scheme that is used on
Blu Ray discs...

It can be done.
