irrational exuberance
Authored by: CarlosD on Mar 21, '06 09:02:21AM

You are right, in part and you are wrong, in part. ;)

5.1 digital audio (aka Dolby Digital, AC3, a52, et al.) is compressed. However, Mac OS X can deliver the stream straight from the DVD out to the digital optical output. If your machine has optical out (PowerMac G5s or Intels), you will see an Audio Output option in the DVD Player's Disc Setup preference. Select "Digital Output - Built-in Audio" and the 5.1 stream is sent unmodified.

The Windows drivers for the USB card I have allows the digital stream to be fed from DVD -> USB -> Optical Out (for XP and 2000). Unfortunately Mac OS X's DVD Player only does the direct digital out trick with Built-in Optical out, not USB.

I am now looking into whether VLC will allow me to route the 5.1 stream through USB. Wish me luck!

p.s. Yes, I can spell exuberance! :D
