When recording companies put copy protection on visual and audio
material, they do so by setting the high order bit in the time line
channel. This means every frame of a video and the whole of an audio
has this bit set and whether one may copy the material to anything at
all depends on whether the device reads the timeline channel and
abides by the setting of the high order bit. Almost all manufacturers
abide by the International protocols for copy protection. At one time
there was a German company, Formac, that made a device named Studio
that created its own timeline overwriting the media timeline. I have
been unable to make contact with Formac to arrange a repair of my
Studio for some 5 years now. One way I would try would be to borrow
some very old computer and CD reader/player equipment that might have
been built before the protocols came on to the scene - of course, that
is no guarantee you would like the result.
