Steve - I am a casual computer user and not well versed with ATAPI or SCSI but I've used Adaptec's CD writer before as part of Widows Media Player. It freezes my screen though every now and then, so, I unloaded it.
I was actually able to figure out how to save my modified songs in winamp and burn them in Compaq's Cequadrat software (another user unfriendly software as you might have heard already). Going this route is quite tedious and repetitious process but that's probably the trade off when it's free.
Thanks for all the info.
