the file that is needed for xcdroast is
cdrdao
try here
http://cdrdao.sourceforge.net/

this also may sort a few probs with K3B...

I upgraded to the 2.6.9-1.11_FC2 kernel, and that solved the problem. Thanks to 'misc' for suggesting the upgrade.

One thing which may save you a little frustration....
When you go to burn a CD, K3b will attempt to unmount your cd for you (if it's mounted), as indicated by messages printed out in the K3b window. This so far has been unsuccessful for me. I had to manually unmount it before I could burn the CD.

Thanks again for the help
