Just recently I have been having problems when putting blank CD's into my
eMac and G4 iBook.

The eMac is set to use Roxio's Toast Lite when a blank CD is loaded in the
drive tray.  However when I try to put a blank CD in to record onto, the
Toast Lite icon appears in the dock for 2-3 bounces then disappears.  The
black CD never shows on the desktop either.  So I can't use the desktops
built-in CD burning abilities.

The iBook relies on just the Desktops CD burning abilities, but as with the
eMac the disk will not show up on the desktop either.

The machines:
G4 eMac 384MB RAM, Combo Drive, Mac OS X 10.3.2
G4 iBook 384MB Ram, Combo Drive, Mac OS X 10.3.2

Have tried the following media:
Generic CD-R (from Applecentre)
Verbatim CD-R
Verbatim CD-RW

Any help appreciated.
