Vixy.net is a cool simple service that lets you convert FLV files to AVI, MOV, 3GP, MP4 (for iPod/PSP) or MP3 rip. It means that you can convert YouTube videos to any of the formats listed above. The service requires the original URL and it sends you the readily converted file once it’s ready. It just became a lot more easier to embed videos into Keynote presentations. :)
