Disable Media Keys
I have just upgraded from 2.2.0 to 2.2.1 on Windows 7 and all of a sudden my play/pause media keys started to work on VLC. (obviously I'd like to keep this functionality disabled)
I think the option to disable this was at
Advanced Preferences -> Interface -> Main interface -> Qt -> Ignore keyboard volume buttons.
I could not find if there is a new option for disabling media key support.
