#5989: Dvd playback problem - PCM DVD unsupported sample depth

Comment(by skamithi):
the problem is that a new PCM format was introduced in ffmpeg, PCM_DVD. on
some dvds, this PCM format is seen in the first dvd cell but no where
else. mythtv is currently not able to switch to the PCM_S16E format that
is used by the rest of the dvd, so incorrectly decodes PCM_S16E audio as
PCM_DVD audio. It doesn't detect the change from pcm_dvd to pcm_s16e as a
stream change, so doesn't close the codec and restart the codec using the
pcm_s16e format.
The latest ffmpeg sync should help somewhat with this problem, on some
dvds, as the pcm_dvd code in ffmpeg was fixed to better handle audio that
should be using pcm_dvd format. and i was waiting for this to happen
before i look further into a fix for this issue.
Right now i cannot look into this issue.
if someone wants to take a stab at this problem and wants some tips on
where to start, email me and i can offer my 2c on the matter.
