To do it youself at home is completly legal and fair use.
It is like hitting FF or Mute.
I think we need to distinguish between RENTAL vs BUY.
If I BUY a DVD for $20 and pay $5 EXTRA for a sanitized edit, which I completly own both copies. That should be legal.
If the studios are too financially stupid to see the market then they are just going to die out.
JUST FYI (exerpting is not always bad)
(b) EXEMPTION FROM TRADEMARK INFRINGEMENT.--Section 32
of the Trademark Act of 1946 (15 U.S.C. 1114) is amended by
adding at the end the following:
``(3)(A) Any person who engages in the conduct described in
paragraph (11) of section 110 of title 17, United States Code, and
who complies with the requirements set forth in that paragraph
S. 167--7
is not liable on account of such conduct for a violation of any
right under this Act. This subparagraph does not preclude liability,
nor shall it be construed to restrict the defenses or limitations
on rights granted under this Act, of a person for conduct not
described in paragraph (11) of section 110 of title 17, United States
Code, even if that person also engages in conduct described in
paragraph (11) of section 110 of such title.
``(B) A manufacturer, licensee, or licensor of technology that
enables the making of limited portions of audio or video content
of a motion picture imperceptible as described in subparagraph
(A) is not liable on account of such manufacture or license for
a violation of any right under this Act, if such manufacturer,
licensee, or licensor ensures that the technology provides a clear
and conspicuous notice at the beginning of each performance that
the performance of the motion picture is altered from the perform-
ance intended by the director or copyright holder of the motion
picture. The limitations on liability in subparagraph (A) and this
subparagraph shall not apply to a manufacturer, licensee, or
licensor of technology that fails to comply with this paragraph.
``(C) The requirement under subparagraph (B) to provide notice
shall apply only with respect to technology manufactured after
the end of the 180-day period beginning on the date of the enact-
ment of the Family Movie Act of 2005.
From a legal standpoint, that's precisely what these businesses do. Every copy they sell has a legal, original copy either behind it, or sold with it. (Don't know which for sure.)
