'/'.join() or posixpath() ? :)

I believe os.path.join is what we need here since we are directly pointing to a
file on the system and not using it in a URL or directing to a server that
interprets the parth...

+    for name in ['bear.mp4', 'bear.ogv', 'bear.webm', 'bear_silent.mp4',
+                 'bear_silent.ogv', 'bear_silent.webm']]
