FLV Video Converter is a free program that offers 2 capabilities in one package: download and convert a single or several YouTube videos at once. Add several YouTube video URLs at once, select the video format you want the YouTube videos to be saved as, specify the output folder and hit the Convert button. Done.
You can convert YouTube videos to MP4 (MPEG4), AVI (DivX), WMV, MOV (Quicktime), 3GP (Mobile), Sony PSP, and MP3. Additionally, the program can also convert the supported video formats to low or high quality FLV video.

Be careful of the size of each video that you want to download and convert, though. The bigger the size, the more videos or URLs you add into the list, the longer it will be to get it done completely. Unfortunately it doesn’t have a pause/resume feature. FLV Video Converter works on Windows XP,98,2003,2008 and Vista.
