Just a standard CD burner works fine - just put the mp3s on it and burn it as a data CD. In my software at least, if you burn it as an "Audio CD" it converts the mp3s back to their original format, so the disc would play in any audio CD player. Then you lose the benefits of it being an mp3 disc, of course.
Our wedding reception music was an mp3 disc burned this way... it was handy to have a 4+-hour playlist on one disc!
Thanks.
