~>>  She said DVD's cannot be erased. Not some DVDs, not some
~>>  catagory of DVDs.

 EC> That was established some time back.  She did not say
 EC> "some" and she did not say "all."  You imported
the "all."

 I *TOLD* you that her comment had to be true for *ALL* or it was
 not true. That is logic 101.

~>>  For a negative to be true in such a case it must be true for all
~>>  elements of the set.

 EC> If it is made about "all elements of the set."  You are
 EC> spinning your wheels in your silly effort to come up with
 EC> some way to quibble with her comment.  And even WITHIN your
 EC> quibble you are not doing it well, since your quibble also
 EC> requires you to put dissimilar items (pre-pressed DVDs,
 EC> DVD-Rs, and DVD-RWs) into the SAME "set" rather than
 EC> different "sets."

 Your ignorance of sets is pathetic. The dissimilar items are
 elements of "subsets". The set is DVDs.

 And you claim to be an economist.

 EC> As Ross pointed out some time back, the
 EC> usual meaning of "DVD" is the pre-pressed and uneraseable
 EC> disk that one buys or rents with data already on it.

 To people with limited familiarity with computers. To the
 computer literate, DVDs are also clearly disks we write data to.

 EC> DVD-RWs are significantly different from them.  So what you
 EC> have been trumpeting for so long as her making an mistake
 EC> may have simply been the two of you using a different
 EC> vocabulary.

 It might have been to the twisted or the simple minded.

 Now pay attention:
 **************************************************************************
 Mimi said it didn't make sense for Ross to record TV Shows on
 DVDs because you can't erase and reuse DVDs.
 **************************************************************************

 In that context, which was the context, everything you have
 offered in arguement is absurd.

 Now, if she meant it the way I said she did, then her comment is
 just plain wrong.

 If she meant it the way you say she did, then her comment is
 just plain stupid.

 Take your pick.
