Is anybody able to burn ubcd (UltimateBootDisk) on their UMBP?

So, I've got both ubcd411.iso and ubcd50RC1.iso and when Disk Utility gets to the verification stage it says that it fails.

Right now I'm burning ubuntu-9.10-desktop-amd64.iso and it seems to be verifying ok. but the others didn't even begin to verify before Disk Utility ejects the CDRW

Burned both 4.1.1 and 5.0RC1 last week, no problems.
