Writing Errors

[silverea]

I upgraded to MicroStudio 2.4 a couple of months ago and have been thrilled with the performance of the program....however, as of today, I keep getting an error message when wanting to write onto a CD...
(Error:'WRITE' command failed on device 0:1:0
Read/Write Error or bad medium detected
04h ooh 02h 03h 0Ch 07h)

I can write maybe 2 or 3 discs out of 10, and the discs I can write, when played on a JVC 800 machine will have broken words in several of the songs...I even tried changing the speed of writing back to no avail.

I have not changed brands of media....I have Windows 98, a Plextor 40/12/40A, I have DirectX 9.0, I'm using the MTU installed drivers.
Could someone please wake me up from my backing up disc nightmare!!!
