OK, thanks for the help guys.  I get the point on aacskeys; need "some
info" in the archive, not the binary itself.  I think I'm getting
closer, but still no playback.  I've edited the KEYDB.cfg file, but
not sure I have the proper format yet.  I guess I'll keep plugging
away.  I'm using "older" blu-ray releases for testing, but can't say
for sure they match the criteria you've listed -- don't know how to
check either.
