On the movie "Les tontons flingeurs" (aka "Monsieur Gangster")

VTS 1 has 3 PGCs, each 2 audios.

PGC1 : AC3 2.0 224kbps, AC3 2.0 224kbps
PGC2 : AC3 5.1 448kbps, dummy
PGC3 : AC3 2.0 224kbps, dummy


PGC2 is the problem for Scenarist. Scenarist complains for the number of channel (and maybe the bitrate, I'm not sure yet).

PGC2 is the "THX logo". A special one, made only for this movie, that's why I wanted to keep it.

My solution was to downsample the Ac3 5.1 to AC3 2.0@224kbps. And of course it woks.

But is there a solution to keep the original audio ?

thats an odd configuration.. if thats the original setup its not a legally allowed dvd audio setup...
what you could do to get around it is do something like this

make it...

PGC1 : AC3 2.0 224kbps, AC3 2.0 224kbps, dummy(448)
PGC2 : dummy(224), dummy(224), AC3 5.1 448kbps
PGC3 : AC3 2.0 224kbps, dummy(224), dummy(448)

when you author in scenarist.. make sure (as i point in parenthesis above) the dummies match bitrate/channels .. then.. after you ifo update go into Ifoedit and go into pgc 2 (VTS_PGCITI->VTS_PGC_2) and edit it like this...


[0000000c] Audio stream 1 status 33280 [8000]
[0000000e] Audio stream 2 status 0 [0000]
[00000010] Audio stream 3 status 0 [0000]


and save it
that makes audio stream 1 access stream #3 (0x82) the 5.1 ac3 and sets audio 2 and 3 to off..

(you can even set all three to 33280 if you want)
