This is the advantage to the new "burn proof" firmware/hardware 
incorporated into some new CD-R units.

All very good and helpful info.  I just wish the CD-R manufacturers 
would have been honest about this from the beginning.  They give a false 
sense of the ease of writing, and speed.  That 8 minute full burn now 
requires, recording to the hard drive first (4-8 minutes), then shutting 
off all "TSR" type programs running the the background, then burning 
without moving your mouse (let alone anything else), then deleting the 
hard drive copy, and then rebooting your system to re-engage the "TSR"s.

Suddenly we have a 1/2 hour process, if it doesn't fail on the first
