I'm also interested in this. How can then Q5/Q10 hold status of "the best 3D BD (ISO)" player when it can't render subtitles as it should?
Why can't you install Vidon application from Google Play and use that instead? I suppose i doesn't support chipset/player on that level and would require external (Himedia) player anyway. But, can Vidon app at least render full BD menu on this box?
