I am having problems with Xine also. Sometimes the audio works and sometimes it doesn't, so I know the config must be right sometimes ;-). I am trying to install mplayer and am having a heck of a time. I went to PLF and followed the directions ( I clicked all the options), but at the end of the install I get the message:
retrieving description file of "mirrors.usc.edu_"...
retrieving source hdlist (or synthesis) of "mirrors.usc.edu_"...
retrieve of source hdlist (or synthesis) failed
no hdlist file found for medium "mirrors.usc.edu_"
examining synthesis file [/var/lib/urpmi/synthesis.hdlist.mirrors.usc.edu_.cz]
problem reading synthesis file of medium "mirrors.usc.edu_"
unable to update medium "mirrors.usc.edu_"
I have no idea what all that means, but I know I have no mplayer. I tried the website download - the package install failed. I am a member of the Mandrake Club and tried the urpmi there with no success. Similar message and I tried 3 different mirrors.
