24 bit lpcm cuts into the video bit budget considerably doesn't it?

Patch looks reasonable. A little overkill for 16bit shouldn't
matter.
Does anyone know how 20bit LPCM audio is packed? According to
http://www.dvddemystified.com/dvdfaq.html#3.6.2 LPCM of 16, 20 or 24
bits (at either 48k or 96k) is allowed.
Should the checks be "==24 || ==20" so the alignment is the same
for 20 and 24 bit?
Cheers,
Steven Schultz
