There is another (working) link:

using the opportunity to remind the list that the corresponding optimized
libtheora is available at konvalo.org, along with mplayer.theora-mmx which
seems to be the fastest decoding tool available for theora right now anywhere.

(it is compiled and setup to work on any Linux 2.6 distro, as well as
