Have you tried FREEMAKE VIDEO DOWNLOADER in combination with FREEMAKE VIDEO CONVERTOR ?
When installing do the custom installation and do NOT accept all the extras. I also use Freemake Audio Convertor but since a year or so have to pay 12 bucks for that one. All in all they do al the things that I want though.
Check out www.FREEMAKE.COM
