As far as I know, there aren't actually any tools for encoding to VP3 
on Linux. The ffmpeg project has a decoder. We've made some changes to 
the original VP3 format when we ported it to Ogg which is why we're 
calling it theora. You can of course use theora alpha3 to encode videos 
on linux.

If you want traditional VP3, you can use the Quicktime or Video for 
Windows plugins at http://www.xiph.org/~mauricio/ on MacOS or Win32. 
Also, the files produced by theora alpha 3 can be converted to 
traditional VP3 without any loss of quality; it would be easy to write 
such a thing if you really need to produce VP3 (in a quicktime or avi 
container) on Linux. We'd rather you use Theora in an Ogg container, of 
course. :)

Hope that helps,
