Startup Disk Creator won't burn to DVD-ROM

[Samuel Reisman]

I downloaded the Backtrack 5 R3 ISO and I wanted to burn it to a 4.7GB DVD-ROM I have, but it wouldn't even recognize the disk. The disk would just sit there whirring, and nothing would happen other than Startup disk Creator freezing. I had to kill it from the System Monitor. I also had this problem with the Ubuntu 12.10 ISO and the Ubuntu Studio 12.10 ISO

INFO:
1. Ubuntu Version: Ubuntu 12.04 LTS (on both LXDE and Unity 2D)
2. Package Version: usb-creator-gtk 0.2.38
3. Expected to happen: I expected to be able to burn the ISO to the DVD-ROM to make a bootable disk
4. What happened: It didn't even recognize the disk and sat there whirring at me, while freezing the application
