Don't be ridiculous, of course they can play 44.1 KHz Audio directly from
the optical read/write disk.  Do you *know* how slow a compact disk *really*
is?  Well, I do...  44.1 KHz * 2 channels * 2 bytes per sample = 176.4 KBytes
per second, or around 1.45 Megabits.  The disk won't have any trouble at all
keeping up.  Now, it will run out of data in 30 minutes or so.  By the way,
someone earlier seemed to think that the capacity of a standard compact disk
was around 50 minutes.  Nope, 74 minutes is the standard, and if you are very
carefull in pressing to get good tracks all the way out to the edge, you can
squeeze 80 or 81 minutes.  (Compact disks play from inside out, and 74 minutes
is a limit to allow for pressing flaws around the outer edge)
