The multimedia bonus disk may not help you with your vlc problem. But it is cool to have.
It's never been tested against Vectorlinux-light as that is just out, so I don't recommend using it if you are on the OS.
If you are on Standard however, you can get it from here for free.

For output control, in VLC go to tools >> Preferences, click on the Audio Icon, Select "ALSA audio output" as the Output module:, then you will be able to select from detected devices in a dropdown selection window.
