IDVD/IMOVIE software

Last weekend, I decided to reinstalled Mountain Lion (clean install) on my Imac and Macbook. Before that I had upgrade to Mountain Lion from Lion. Until the clean install I had Idvd, I moview, etc. After the clean install, these softwares and others are gone. Is there anyway to download them free or any way to retrieve them from the Lion installation disk that i have?

Thanks.
