I am wondering if anyone knows when DVDs of Malcolm will be availible, other than season 1. Or, does anyone know where I can download them from? I tried kazaa but not all the episodes are there.

Not anytime soon. There was recently an article posted on the internet (there's a link to it at tvshowsondvd.com) which explains the problem. While Season 1 sold well enough to justify future Malcolm DVD sets, Fox is having problems with music clearances, so it could be awhile before we get more Malcolm on DVD :(
