Yes, the playback of MXF files works on latest VLC.
In fact I started a PhD to speed up the JP2000 decompression stream for 
digital cinema, through the openjpeg library.
The decoder will be free and opensource ( more info in english :

)

And we select VLC for the player, at the beginning for playing DCPs and 
then use the VLC interface to create show play lists

I can have several MXF files : one for sound, one for image, one for 
subs. May be the input-slave can be the good choice.
