Hi Monty, hi all,

thanks for the fair comparison, we are glad the two projects have 
meanwhile found a good way of communication, based on mutual respect. 
Vorbis is my favourite audio codec since a long time for most of my 
private video compressions, and i guess it will stay that for a long time.

Good news : in next MKVtoolnix we plan to release Theora-in-MKV support 
publically. Note that current matroska DShow splitter (Haali splitter) 
has support for these files already since 2 releases, so once people can 
make such files with mkvmerge they should play on most PCs without any 
problems, if ffdshow-video or Illiminable's theora decoder filters are 
installed. For VLC, support is planned to come soon.
