Subject: Re: DVD question
Lawrence and List,
It sure seems to me that if a computer can play a DVD movie from a
DVD-ROM drive and this requires the movie to be decoded (either in
hardware or software) in the PC before it is displayed, then even if
there is encryption, the data must be decrypted BEFORE it comes out of
the DVD-ROM drive (I'm not talking about the mpeg decoding done later).
Why can't that raw data dump out of the DVD-ROM drive be stored to a
file and then have that file "played back" at some future time as though
it had come out of the DVD-ROM drive?
If I understand it right, a DVD movie is only on the order of few Gigs
and I don't see why it couldn't be stored on a large HD (even if only to
be viewed and then erased). It seems to me if this is possible, the
Libby would make a wonderful portable movie player to take for a child
to watch while waiting for a doctor's appointment, to watch on the
plane, etc. ....
I don't know the legalities of this, but I am not talking about piracy
(at least as I understand it). I own the DVD-ROM movie disk(s) (paid for
them with real $$$) and would just like to view a movie on the go. What
difference should it make wether I have the disk in a DVD-ROM drive or
playing it from HD? It seems to me that few Gigs of movie could be
transferred over a fast eithernet in a few hours (start it and let it
transfer over night). Maybe not that practical for a day to day thing,
but certainly acceptable for doing occasionally.
Regards,
Clinton Parker
