Hahahaha... "Do you want to keep the deluxe vacation you've won, or do you want what's in the box

I know that PCM was never used for DVDs, so I can't use DVDs as a guide. I'd prefer to use the most 
'universal' flavor of PCM coder. Do you have any recommendation, or is pcm_s24le it?

Or is little-endian versus big-endian a non-issue?

Note that the LPCM source is 24 bit.
