Question about a tv show I like?

I really like the show What I Like About You. I REALLY want to buy the seasons. But I can only find the first season. I don't want recommendations of where I can watch the episodes, I just want to buy the seasons. Is the second season even out? Is it going to come out anytime soon? I was also wondering if it is not out yet, that it's the same reason as why there is only one season of Malcolm In The Middle out. There was only one season of that out because they didn't have the rights to the theme song or something. Is that why there is only one season of What I Like About You out on dvd? Or is there a different reason? Thanks in advance!
