Tony,
Everyone understands this.
The confusion comes because someone (Jason?) said that they
_captured_
losslesly...
... when it was asked how (ie - did they have a decoder with a digital
out), this got modified to "No - I capture in analogue, and use lossless
compression of that".)
Then the shouting began.

Pkzip etc use
compression where, yes, data is removed - otherwise it would
not be
compressed!!
BUT at decompression, that data is recovered to create an
exact copy of the
original.
With Jpeg/mpeg2 etc, data is removed that
CANNOT be recreated - is this why
there appears to be some
confusion?
BOTH methods do lose data when the file is compreseed, but
one
of them can
recover that
data.
