Media Convert, keeps the family united

Found this one yesterday, while trying to see a family video they sent me, of course, created, or at least, edited with Windows software.
VLC belched while opening, so I was about to install Flip4Mac, but, for what I read it wouldn't work either.
Googling a bit found this site, that will convert any video to a any format, for free, there must be a size limit I'm sure (not to mention the privacy concerns), but for the need I was, it was excellent.
