CD Burning Always Fails

I have two CD/DVD RW drives and no matter what I do I cannot get a burn to go
through using the native Vista burning. Basically it says it is adding files
to the image, then as soon as it prepares to burn it throws up an error
message that says, "There was a problem burning this disc" "There was an
error burning this disc. The disc might no longer be usable."

I have the following drives:

Plextor PX-760A (latest firmware is installed - v1.05)
LG GSA-4163B (latest firmware is installed - v1.05)

This is happening on the x64 RTM Ultimate Edition of Vista (MSDN)

I don't see anything in the event log (but I might be looking in the wrong
place).

Can anyone help me out?

if your trying to burn files to a re-writeable cd or re-writeable dvd, you
should click on the first option you see which is "live" then that cd or dvd
will be ready to write to again and again.

if your trying to burn files to cd's or dvds which are not re-writable, you
should click on the second option which is "mastered".

you should though see this window that appears when ever you put a blank cd
or dvd in. if not go to computer, right click cd or dvd drive, then click on
explore. then you will see the option window.

i wasted a few cd's and dvd's before i found out. and those cd's of yours
saying they are no longer usable, are no longer usable.
