I'm on Windows SP3. If I press Ctrl-Alt-Delete during playback, VLC 1.1pre2/pre4 will crash silently, but immediately. 1.0.0 GoldenEye does not crash.
Crashing happens regardless of video type. I've tried playing several videos of different formats: flv, avi, mpeg, dvd. Audio files do not cause a crash.
When I reproduce this crash through vlcj, the Dr. Watson error cites libmemcpymmxext_plugin.dll.
Let me know if you need more information.
