I have a cat that won't stop walking on my keyboard while I'm watching big bang theory, now it has delayed the audio, changed the aspect ratio and I got some Asian language subtitles.
How can I disable keys in VLC doing this?
Not directly. But you can set everything to the same key combination. By doing so, every hotkey will become unset except the last hotkey, which you can set to be something like ctrl+shift+q. your cat won't probably step on this combination at the same time.
