Oh! One thing I forgot to mention, in case anyone else stumbles on
this thread. I had to re-install VLC using their installer, to get it
working. Using the portable version (simple zip file) wasn't working.
I had been upgrading with zip files overwriting previous versions, but
hadn't been using the plugin until this thread. I noticed during the
install that it updates the plugin. By using the portable version,
the plugin dll wasn't getting updated - which seems to be what causes
the black window with no output. The plugin loads, but it can't find
all the other bits of vlc to be able to decode and playback.
HTH
