mkv to avi programs
 

I have gungrave in dual audio but I want to extract only the engish audio and make it into an avi so that it will be simpler to transfer into a dvd. There are alot of other series that are dual audio that I wouldn't mind making into avi.
Its just easier to handle avi files and plus it saves space.

I've tried some programs like alltoavi, ogm to avi, and riverside but those programs have failed me.
I would be appreciated if someone were to point me in the right direction.

try mkvextractgui to split the mkv files into parts.
