Unfortunately, megaspaz's advice is not quite correct. Making symlinks won't make rpm happy. You need to install a binary package so that it appears in rpm's database. I'd suggest visiting the official MPlayer RPMs website: http://luna.cs.ccsu.edu/dominik/mplayer/ (US mirror).

Please read MPlayer's excellent docs before using it. The syntax for playing DVDs is mplayer dvd://N, where N is a title number.

Sorry for the long time to reply, as other projects had been reserving my time. Anyway, I'm now working with the Xine DVD player and tried to play a DVD. It went through the FBI warnings and the disclaimers, but when it reached the first chaper of the movie, it crashed with the message "Error reading NAV packet"

What does does that error message mean? And what can I do to fix it?

Thanks for you time.

Here's a log of all the output in the terminal:

hi. not sure what it's like on other distros, but i just had a bit of hassle setting up the libmp3lame.so module for Audacity on debian.
just thought i would add this post in case it happens to help someone

from other posts in this thread it looks as though on RedHat when you build the module from source it gets put in /usr/lib/
i couldn't find my libmp3lame.so module for hours. turned out it was in /usr/local/lib/

some of the info i am about to provide kind of doubles up on things already said in this thread, but for anyone who requires Debian specific help:

download lame source from http://lame.sourceforge.net/download/download.html (thanks megaspaz)


tar -xvzf lame-3.96.1.tar.gz (assuming you choose to use 3.96.1)

cd lame-3.96.1

./configure

make

make install

cd /usr/local/lib/

dir libmp*

libmp3lame.so and a few other similar files should show up
hope this saves someone some time
