I'd say the 1.0 theora encoder is generally below xvid in quality for web video bitrates. The current thusnelda encoder is somewhere between xvid and x264. -r

If you want to convert a WAV or Flac file to Vorbis, you can use OggConvert, which is available from the repositories. Remember that it's of no use to convert MP3 files to Vorbis, because the quality will never go up. Any re-encoding will, by definition, only deteriorate the quality. MP3 has a few issues even on the highest settings, which will not go away if you encode it to Vorbis later. I don't know about any GUI program that can convert video files to Theora with the new Thusnelda encoder. OggConvert can convert video files to Theora using the old reference encoder, but that gives absolutely awful results. You may need to use the experimental Thusnelda version of the CLI tool ffmpeg2theora that has been made available: http://lists.xiph.org/pipermail/theora-dev/2009-May/003902.html Remco
