Hi James Courtier-Dutton!

I modified the libdvdnav for mplayer:

dvdnav_get_audio_attr()
dvdnav_get_spu_attr()
These sherve to the mplayer can query the audio, spu language code and
the audio type (stereo, 5.1, dolby digital, etc.).

Because of the still frames decoding error so get needed the repeat of 
these pgc-s this is way I created new functions:
dvdnav_still_back() - repeat of the still frame cell (pgc)
dvdnav_wait_back() - repeat of the cell (pgc)
(but this functions don't reprocess dvd pre-commands)
dvdnav_wait_still_clear() - end of the repeat
dvdnav_is_still_cell() - Is it a still frame? (it doesn't probably need)
dvdnav_button_auto_action() - enable/disable of the button auto action

At the cell change event to processing the mplayer needs to deterimne 
if the change is real or only repeat:
dvdnav_get_pgc() - quering of the current pgc number

New functions sice my last post to devel mail list:
dvdnav_get_active_audio_stream()
dvdnav_get_active_spu_stream()
If menu spu id not default then mplayer query the spu id that's way mplayer 
show correct spu.

Best regards!
