10. VLC media player (Open source/All platforms)
 Ok, so VLC is a media player, not converter, but if you're watching digital video, it's a must-have—plus VLC can indeed rip DVD's, as well as play ripped discs
 in ISO format (no actual optical media required.) VLC can also play FLV
 files downloaded from YouTube et al, no conversion to AVI required. 
Since there's a portable version, VLC's a nice choice for getting your DVD rips/saved YouTube video watching on wherever you go.
