[Brian Meyer <briantmeyer@xxxxxxx>]

I have made changes to vlc.py seems to fix this issue.

It is able to handle vlc not being present, or the 64 bit version being
installed.

To use VLC it requires the 32/64 bit version, or the 32 version of vlc.

If not present, it marks VLC as disabled ( which grays out the checkbox
in the UI and switches the enabled option to webkit )

I don't know how to make this work in vlcplayer.py, it seems to need to
need a try statement around the initial loading of the DLL, but assuming
we can edit vlc.py, this should fix the issue.
