Perhaps that's true. But you could try to run QuickTime Player. It emits that dreaded FIXME and *the whole screen* goes black.
Will try when I come back home (d/ling this on a pay-per-the-minute dial-up access is a bit hard :-) ).
Lionel, could you look at that problem? (QT player is a free download from Apple).
Last time I tried this it was with my old sound card with Wine crashing the whole box when playing a sound (so I stopped debugging it).
