You are currently using Xandros...unless you have wiped it already. You will learn (if you install another distro) that Xandros is very slick out of the box compared to every other distro out there. MP3s work out of the box, MPEG, AVI, etc....all work. Better yet, you get out of the box video card drivers installed (at least for nvidia), and unmatched samba implementation. With popular distros like Fedora and Ubuntu, you will have to set this all manually.
HOWEVER, both of those (Fedora and Ubuntu) have the best user documentation I have ever seen. So if you choose to install anything other that Xandros....make it one of those to and bookmark these two sites:
*Both of those will tell you EVERYTHING you need.
One last note: If you want to merely fix your Xandros Networks, do this:
1. Open a command line and type 'su -', then enter root password.
2. Type this: 'vi /etc/apt/sources.list'
3. Make this file look like this:
xandros3.0-xn main contrib non-free
unsupported3.0-xn main contrib non-free
4. This is the default, so it should work. remove any additional lines by moving the cursor to the beginning of the line and type 'dd' to delete the whole line.
5. Hit escape and type ':wq' to save it. Then try to fire up Xandros Networks again.
Hopefully you get something out of that rant....my first contribution to a linux forum.
