Or rather, video purging.
I want to burn some anime I’ve had in my HD for too long, but first I would like to see if I can remove the english dub from the files in order to save space… and because I’m never going to listen to them anyway. They are all .ogm and .mkv files.
Is there any program that might let me do this with relative ease, or is this too complicated and I need to start researching all over the place?
