A one-line command to install most of the needed multimedia stuff.....

Code:
pacman -S mplayer mplayer-plugin xine-lib xine-ui libdvdread libdvdcss alsa-oss



NOTE: Add user to the "audio" and "video" groups.
Code:
usermod -G "audio,video" USERNAMEHERE


Open up KMIX and adjust the audio volumes.....

On that usermod thing...I'm not getting the "video" group. I tried the command both with and without quotations around the [video] part......(I'm already a member of audio).

just edit /etc/group, find the line that looks like:
Code:
video::27:

and change it to
Code:
video::27:lberg

(the gid may be different, I just ripped it from my box)

log out and back in for the changes to the groups to take effect.

Thanks, guys. Nukes, I looked in groups.conf, and video was right there......then I logged out and back in, and iIt ended up that once I did the -aG, it wiped all my other groups BUT video and users....So then I did -G audio,optical,video,wheel,storage,users lberg and it worked. Tested it out with the "Cars" DVD....Worked perfectly, thanks for the info, crouse.

Code:

DESCRIPTION
       gpasswd is used to administer the /etc/group file (and /etc/gshadow file if compiled with
       SHADOWGRP defined). Every group can have administrators, members and a password. System
       administrator can use -A option to define group administrator(s) and -M option to define
       members and has all rights of group administrators and members.

   Notes about group passwords
       Group passwords are an inherent security problem since more than one person is permitted to
       know the password. However, groups are a useful tool for permitting co-operation between
       different users.



Code:

USERMOD(8)                            System Management Commands                           USERMOD(8)

NAME
       usermod - modify a user account

SYNOPSIS
       usermod [options] LOGIN

DESCRIPTION
       The usermod command modifies the system account files to reflect the changes that are
       specified on the command line.



Basically BOTH commands work ..... I just like usermod because it's originally setup to work on ONE user account at a time.....so if i fubar something, I fubar one account.........not an entire group Wink
