This is completely wrong, lpcm_header_len is only 
valid for DVD-A so it cannot be used to identify it.

Iiuc, vlc only uses the absence of lpcm dynamic 
range control to detect DVD-A (or do I misread the 
code?), I suspect this is not completely reliable.

DVD-A files are apparently always audio-only while 
DVD program streams always (?) contain a video 
stream, perhaps this should be used to identify 
DVD-A?
