SegaXtreme

I downloaded the recommended burning software. Works fine testing speed, then it gets to actually writing the files. all goes well until about 2/3 of the way through, it gives me some bullshit error, spits the CD out, and I have to start again. It does this everytime. I'd use different software, but the only FAQ on burning CD's that's easy enough to understand only gives an example using that program. What can I do?
