I did 

cat stream_dump | extract_a52 | a52dec and the sound played fine

in mplayergq's incoming I made a subdirectory

incoming/dvd_with_unplayable_ac3_bug

and put the first 28 MB of the decrypted stream as generated by 
mplayer -dumpstream

The first few seconds are silence, but there is sound at the end (explosion 
and some talk) - mplayer shows the same output as it dows when playing 
directly from dvd, it also mis-detects the aspect ratio.
