Tested in Safari 3.0 and 3.1 on Windows XP...
OggHandler currently detects the Java plugin in Safari for Windows even when it's not present. The player thus defaults to attempting to load the Cortado applet, which then pops up a big ol' dialog box prompting to download Java.
QuickTime mode can work... more or less... if XiphQT components are installed.
