ogg to mpeg

I am trying to convert some of the http://www.thesourceshow.org/node/11
  files into something cinelerra can edit (mpeg or dv)

like this one:
http://www.archive.org/download/AaronNewcombEpisode1-_TheFilesystemMenace_-December23_2006_theora_/episode001_lg.ogg

It isn't erroring, but it isn't converting either.
