I think what he means is that it should display the information of the
current track, not all available... the same as for your hardware dvd
player.

Currently, when pressing '#', in the OSD it shows '(130) en' or
something like it, while it would be nicer to have '(130) 5.1 DD en',
which AFAIK is known to the current process.


BTW, and somewhat off topic: is it possible for the program to determine
if a stereo (two channel) audio track has a surround flag set or not? I
remember in the olden days, the audio-part of the output printed
something like
========
Opening audio decoder: [ac3] ....
..
AUDIO: 48000 Hz, 2ch (stereo), s16le, 128kbit yada yada yada

or

AUDIO: 48000 Hz, 2ch (dolby), s16le, 128kbit yada yada yada
======

but this behavior has gone away. I used it back then to fill with it my
DVD database with the correct track information (hence also my
cropdetect-patch with the measured aspect ratio), and nowadays I'm stuck
at believing the back side of the DVD case.

it could display something like
(n) 5.1 DD <lang> for 5.1 Dolby, or '5.1 AC3 <lang>'
(n) 5.1 dts <lang> for 5.1 dts
(n) 2.0 DD <lang> for 2.0 stereo
(n) 2.0 DS <lang> for dolby surround

is there a way to detect if 5.1 Dolby Surround EX is present in a track
(that with an optional rear center channel matrixed into the both rear
channels)? And also for dts-es, where there can be either 6.1 channels
or 5.1 also with a matrixed rear center channel?




One thing I also miss is the default display of the number of available
chapters. Initially, number of titles, chapters for this title and
angles for this title were displayed, but now only number of titles and
angles for this title are displayed (ok, for DVDNAV this is a different
story altogether, b/c no number of titles is displayed at all)
