I have seen questions on about any freeware software to convert MKV with multible subtitles streams to DVD. You can information on the www.matroska.org.
The freeware software can be found at the following sites:
Mediacoder http://mediacoder.sf.net (Not easy but powerful)
avi2dvd http://www.trustfm.net/divx/SoftwareAvi2Dvd.html
Superv2007 http://www.erightsoft.net/SUPER.html (processor intensive)
