handbrake 1.4.2-2 owns /usr/bin/ghb, the first command says there's no package owning /local/bin/ghb. If I run just "ghb", for some reason it's looking for it in /usr/local/bin and since it can't be started, that brings up the error about libvpx.so.6. But if I run /usr/bin/ghb, then handbrake starts ok, that's why I figured that if I edit the desktop file to point to the new location, it should fix the problem. Which I did a moment ago. IDK if that's the right way to do it, but at least it works.
