I like MediaWiki.

[edit] My MediaWiki

I have installed MediaWiki on FreeBSD 6.2 and FreeBSD 7.0, it works well.
Exemplar of my install: JS Wiki

[edit] Video; ogg/theora

Maybe I am an idiot, but I can not figure out a proper technology stack to produce and incorporate proper open source video in my wiki.

I would like to use all *.ogg for audio and theora for video. If people have help in remedying my idiocracy it would be much appreciated. — MediaWiki
