I've started DVDx 4.1 coding to include full-featured player from Starbuck's FreePlayer, libSB is stable enough (available in libSB-src.tar within freeplayer-18.104.22.168-src.tgz).
Starbuck's FreePlayer 1.0 is now stable on Windows and Mac OS X.
What's new in 22.214.171.124 release:
- DVD menus with navigation and audio/subtitle control
- support for non-western subtitles: Chinese, Japanese, Korean, Vietnamese, Greek, Cyrillic, Arabic, Hebrew
- user settings for subtitle font style (font color, font size, bold, shadow, bottom margin)
- deinterlacing video (switchable on-the-fly option)
- option to turn on DVD/VOBsub antialiasing (-spuaa 4 -spugauss 0.5)
- menu to associate audio/video/playlist file extensions to FreePlayer (every extension can be selected/unseleted and be restored to previous application associated with)
- and more fixes (see FreePlayer changelog)
