maybe one osd where:
1st 'page' is the simple control bar at bottom where basic stuff goes in (play/pause, ff/rw, volume/mute). user can perform the basic things and then leave osd if desired. also it contains buttons, or tabs if you like, to the other pages
2nd page is maybe a more advanced (larger?) version of page 1 for filter and delay settings and such. don't know but i think audio+video settings could be one page.
3rd page subtitle settings
4th codecs fps cache info
i'd happily do some kind of images to examplify ideas, mine or others?
some side notes: i really like the way delay settings was handeled in xbmp where osd didn't have to be involved to achieve it. badly synced subs and audio/video out of sync is the biggest problem for me when watching movies. maybe this could be done in both "guiwindowfullscreen" and osd?
in xbmp volume wasn't possible to control with the dvd remote. so obviously i'd like that too
