Unable to Burn Backtrack 4 live CD

I am trying to burn a copy of backtrack to make a live CD. When trying to burn the disk in both CdburnerXP and PowerISO and both come back with different errors but both basically say they cannot write the iso to disk. I've changed the disk and this makes no difference.

When i try to burn another iso it works perfectly...

Any help would be greatly appreciated

Try checking md5sum of the ISO, if it does not work try running BT from a live USB/VMware/VBox, or just ask someone to burn the iso for you.

BT4 will not fit on a CD. Burn it on a DVD.
