The physical matter is irrelevant. I am perfectly entitled to own, shape
and fiddle with sand and bits of metal. If I wish to remove the software
from the tivo, melt it down and cast the result into the shape of an
obscene gesture and wear it at the tivo shareholder meeting so be it. At
that point it would be my work made from melting the tivo that was the
protected work - same matter.

Each copy is an instance of the work. My copy does not change its status,
nor its legal situation if someone rounds up every other tivo and melts
them down. I guess if you want to be pedantic the Tivo contains "an
instance of the work"

We have every legal right to do so. I am perfectly permitted to try
to grant you the right to reproduce my work only if you pay me $25 and the
reproductions are provided in a silver box with flashy blue lights. I am
perfectly permitted as author of a work to tell you "no". You as box
maker are perfectly at liberty to tell me where to go stick my offer and
just not use my work.

I can influence your hardware all I like. What I cannot do is influence
you in any way if you decide not to take any action involving my
copyright. Nor can I through copyright require certain kinds of condition
(eg control other works on the same media) as that requires contract law
and a proper contract, nor certain things that are deemed to be unlawful
by the state (The GPL gives me the right to modify the code to break into
the DoD, steal all their secrets and mail them to the Iraqi government,
the law of the USA not unsuprisingly takes that right away).

Ok I guess thats a question of level of abstraction, like being "an
instance"

The Lawyers don't. As experts in their field I generally trust their view
on this. Also remember that lawyers assess legality not morality so there
are other questions to ask than "will I get sued".

Agreed. But GPLv2 has many absurdities such as the way it handles
copyight notices. It wasn't designed when GUI apps were the norm, it
predates web hosted services and the GPL mobile phone was, I suspect, not
on the drafters radar let alone in their pocket.

If my toaster is ROM based then it is difficult to argue that the
preferred form for modification is anything but the code and usual build
files. If the system is writable then it is possible if not reasonable to
argue that the preferred form includes the information needed to load
that modified image, or should do so.

What this means for the FSF goals if Tivo get up one morning and switch
their system firmware to ROM however is interesting 8)
