It doesn't help.

I guess this br could be totally untypical or even broken because
linbluray can't handle it properly (it doesn't manage to pick the
english version).

I recall ages ago uploading a bit of this for another issue which still
exists. Lipsync (with or without lavf) is correct at start but out by
first dialogue. Testing now it seems that the number of decoding threads
affect how bad it is.

Interesting but may be unrepresentative/broken, anyway if 911meg isn't a
problem a dumpstream -
