As I mentioned previously, I've been having issues burning CDs after doing a clean install of Tiger (10.4) and updating to 10.4.1.
I came across a thread on the Apple Discussion boards tonight, which seems to have fixed the problem! Yay! I have no idea how this affects disc burning, but it works, and that's all that matters. 
Thanks to "Pete" for the solution to this problem:
open system preferences.
go to international
under languages: drag any of the other languages to the top, then drag english back to the top.
make sure "order for sorted lists" is set to enlish
make sure "work break" is set to english(united states, computer)
then restart.
The details on the fix are here.
