[ydl-gen] PS3 Yellow Dog 5.02 DVD Playback

[Thomas A. McGonagle]

Hi Fellows,
 Thanks for the replies. Bill I appreciate your need not to discuss this
issue. Would it be inappropriate to ask general questions about libdvdcss,
and libdvdread?

 I am a little confused as to how they differ. I have both libraries
installed on my PS3. Norberto suggested a Ubuntu resource that discusses
installing both libdvdcss2 and running a script from a libdvdread3
directory. I checked out both libraries on Freshmeat, and each of their
respective descriptions says that they can each decrypt css. I installed VLC
and Mplayer from several repos I added to the system. I don't believe
libdvdcss was a dependency of either VLC or Mplayer, and I ended up
installing libdvdcss as a separate yum install.

 Here is the question, would a piece of software like mplayer default to
libdvdread, and then when it saw the libdvdcss libraries start using
libdvdcss? Or would you need to recompile software like mplayer to
specifically look for the libdvdcss and not use libdvdread?

 This is purely an intellectual question. I am afraid I am not a C
programmer, and have never known the answer to this. Essentially will
software such as Mplayer dynamically look for and load its dependent
libraries.

 Thanks a lot for the help. I hope everyone has a wonderful weekend!
-Tom
