Today I downloaded slitaz 3.0 stable and booted it from a live USB flash
Its impressive but I am having two problems


1) How to permanently install mplayer ? off course i need to see videos
2) How to install it to hdd the install option in system menu simply gives an error ........ (some files) not found

Please solve these problems , waiting

1) it's a live session, so it's normal that nothing remains ... that's a good thing ;)
But if you want to keep stuff, you have to do your modifications on live session , than create a new iso . How ? simple . go in menu-system tools - live cd - write iso
It's all

2) for mplayer, keep in mind the missing files name, then with tazpkg gui , search the package or the file name wihout the .so extension, install it.
To use mplayer, in parameter video, switch to X11.
