--- Comment #6 from Erich Hoover ehoover@mines.edu 2012-10-30 12:38:18 CDT --- Created attachment 42333 --> http://bugs.winehq.org/attachment.cgi?id=42333 Fix InternetCrackUrl parsing URLs containing a semicolon.
Well, apparently this was easier to look into than I thought (though I really shouldn't have taken the time anyway). It looks like InternetCrackUrl should not consider a semicolon as the start of "extra" data (see attachment). With this fixed then Netflix will load properly without native wininet.
Note: You still need to work around Bug #31858, but you also need to make sure you don't move the mouse over the player until it's finished loading - this causes it to lock up for some reason.
