Lol @ this thread. OP, you were unlucky enough to get targeted by thewebcat, who's a troll of a humongous scale. It's better not to even try to argue with him and never to trust anything he says. He unbanned you three minutes later, by the way.

In any case, if all you want to do is cut some MKVs, you can use mkvmerge GUI to do that, picture related. You can then use the append function to merge files together.
