iVideo Converter & Downloader
Full user review
"Powerful video converter and downloader."
Very easy to use, you just search for the download you want, the you can download with one-click. I like that you can choose the format you want to save your file to. MP3, AAC, FLAC, MOV, AVI, MP4, etc. Pretty cool feature for a free software.
None so far, I really like iVideo Converter
