So I'm trying to burn this masterpeice to a CD.

$ crdao write tofile.toc

... ok here we go. It works, but then when I try to read the disk back, i get tons of CRC errors.

"5 Q sub-channels with CRC errors" .. etc etc.

Someone On The Internet (tm) said thusly:
http://linux.derkeiler.com/Mailing-Lists/Debian/2005-04/1370.html

OK, so I try to write at a lower speed.

$ cdrdao  write --speed 4 tofile.toc
Starting write at speed 8...
Pausing 10 seconds - hit CTRL-C to abort.

No no no no, I said speed 4!

$ cdrdao  write --speed 2 tofile.toc
Starting write at speed 8...
Pausing 10 seconds - hit CTRL-C to abort.

Arrgggh...

$ cdrdao  write --speed 1 tofile.toc
Starting write at speed 8...
Pausing 10 seconds - hit CTRL-C to abort.

Hey, cdrdao, are you even listening to me!??

So, two questions:
	1) Is there any reason to burn an audio CD at a speed < maximum, or is this the dreaded digital voodoo?

	2) Why is cdrdao refusing to do what I tell it to do?

Thanks, all.
