Hi, matroska video (mkv) is a 'wrapper' containing a video file and usually (but not always) an audio file.
You need to install a player that can play native mkv files, or alternatively (my favourite) is to install a 'splitter' that works invisibly to unwrap the file every time a program or player (eg media player) opens it.
so these programmes

mkv2vob
will they keep any of the HD quality on the dvd disc ? as I see PleXo says you will loose HD
as I see some films on NG's that say super high quality and wondered if thats what they do to make a film higher quality ?
if you have a blu-ray burner i dont think you will loose any quality but i dont have one i have been encoding mkv to trp files for my tm6900 but been useing mpeg2 got to play around with settings to encode to mpeg 4
