Dunno. I just discovered that there is a cdrecord man page (see last
response to Dave). I need to read up on cdrecord and learn the basics
of using a/the cdwrite features...

Where are these flags set?
/etc/make.conf has these USE flags:
"-gtk -gnome java qt kde dvd cdr sse mmx 3dnow alsa 
apache2 calendar cups divx4linux encode ethereal acc 
jack perl php postgres spell ssl tiff xv java ffmpeg
mplayer v4l dvdr jpeg lm_sensors quicktime xmms xvid 
mozilla mpeg scanner doc xine theora"

I need to learn how to use any simple cdrecording commands
(syntax challeged user here) first. Then I can worry about
all sorts of fancy file types/formats. I'd be better off
downloading a know file to write to the device (ascii text?)
or something on the gentoo system, just to build a little 
confidence. I need a newbie 'how to cd burn' before I worry
about the intricacies of audio recording files on CDs.

I'm going to read the cdrecord man pages. simple syntax examples
or a link to a document to any cd burning software is what
I need.
