Does anyone know how this is done, I know playing UT2004 under windows you hit F11 to pull up the playlist editor and just add songs, but under Linux I open the playlist editor and I cant get the playlist editor to let me browse to my mp3 folder to add songs, do I need to put the mp3's in a specific folder or create a playlist and put it in a certain folder to pull it in?

It was my understanding that the music player in UT2004 only played .ogg, could be wrong though.

I know that playing UT2004 on Win2000 I can play mp3's but it may be that it only plays .ogg files on Linux, but my real problem is I cant get the playlist editor to navigate past the root ( / ) directory and I'm not that keen on the idea of moving my music collection to my root directory.

I'm pretty certain UT2004 on linux only plays .ogg files. (This is probably due to crazy licensing things involving mp3).

As for the playlist in UT2004, the problem adding files is that you can't navigate your file system. This has to do with sandbox security. No matter though, you can simply make a playlist by editing the UTPlaylists.ini file. (It should be ~/.ut2004/System/UTPlaylists.ini). You can edit it yourself or just use this Perl script.

If you're going to edit it, just add a block like this:
(Note that a playlist title can't have any spaces in it)

Also you don't need to copy over your ogg files from another directory. You're using Linux remember? All you need are symlinks. What I do is I create a directory of links to ogg files to use as a playlist, and then I create a playlist from the directory. So I have a directory of symlinks for each playlist. Remeber, to create a symlink use (use "man ln" for more info).
