AC3 isnt all that special, its 384kbps (128kbps per left-right channel, or the
same as MPEG audio). AC3 doesnt (or didnt unless its very recent) have any
provisions for variable encoding/decoding rates. I'd prefer DTS in this case,
much higher quality, 20bit audio, 1.544Mbps bandwidth. But that lands us in
the area of local delivery for theatre systems such as laserdisc.
