 Hi,

 I have been looking at some problems I have been seeing with DVD playback,
 namely that for some DVDs the menu buttons never get highlighted, so you
 don't know which button is active.

 The two main problems I found are the following:

 - the current menu button handling does not work if the menu button
 subtitle image is located anywhere else than the upper left corner of the
 screen because otherwise it will get the screen locations of the
 highlighted button wrong

 - currently the subtitle image background and the highlighted area are
 painted as two separate images; this produces incorrect results if a DVD
 uses button effects such as a greyed out area that becomes transparent
 when highlighted as the transparent foreground image will not undo the
 grey layer from the background image; to fix this the color of the
 highlighted area needs to be set in the background image directly

 I have added a patch with corrections for this and one or two other
 smaller problems. I have created it as a patch series for better
 documentation of what is being corrected. It should be easily processed
 with 'git am'.

 Please let me know if you have any questions.

 Thanks and best wishes,

 Martin.
