My son has lubuntu 10.10 on his pc and he has frostwire on it and all that downloads are mp3 music. He want to burn it on a cd. How to get it to burn? I put the gstreamer transcoder on it but it will not play on cd player.

you don't convert mp3 to anything. you need a cd authoring program.
look through the software center to see what's available.

didn't you post this already and you marked the post as solved?

No but I did post one for downloading from a mp3 player to
put it on a cd. But my 12 year old boy did not explain very
well in what he wanted, I have xfburn and k2b on his system.
I tried one at a time tried every thing (almost) to do this.
He said right after I installed lubuntu 10.10 he burned
a song and it worked but it was on a cd-r and I'm trying
to do it with cd-rw in which should not make a dif.
So I told him that he may have to stick with the mp3 player
to listen with. He loves his music.
Does buntu have a package that has a bunch of music
in it, maybe that is the way to go??

Thanks GREG T., that solved my question.
