I haven't; but I don't think it's relevant, as the same app on a PC running
'ordinary' windows XP works fine - if QT is installed, it uses QT; if QT is
uninstalled, it uses Media Player.

Can RunRev confirm the actual requirements, or give me a clue how to debug
what's not working?  (EG on OS X I now about using the console to get
detailed info about what's failing to work when it tries to access some
external component; is there some equivalent on Windows (XPe) that I can use
to figure out what the problem is here?
