Hi,

I have no idea how to detect this automatically, but the attached patch 
should make it work (while breaking all other DVDs :-( ).
I'm not sure if the line
AF_FORMAT_LE | AF_FORMAT_SI;
is correct, you might have to use one of the three commented-out lines 
below instead.

Conversion should be done automatically.

no wonder. 24-bit is such a brain-damaged format nobody in his right 
mind wants to implement it ;-)
