media-video/qdvdauthor-0.1.0 is built only with xine support but should also be built with mplayer support.
Created attachment 77681 [details, diff] Patch for ebuild to build with xine and mplayer support I've added a patch for the media-video/qdvdauthor-0.1.0 ebuild which builds qdvdauthor with xine and with mplayer support. Btw, I've read the TODO. But as long as the USE flags aren't implemented it should contain support for both players.
qdvdauthor-0.1.2-r1 is in CVS now with "xine" and "mplayer" use-flags.
