No Joy I have Build 3188 and can't burn CDs either. Same as someone else reported. It acts like it's going to start burning, pulls up an error message saying it couldn't write, then virtual XP freezes. At that point I have to quit Parallels and reboot my Mac.
I just tried Deepburner as well. It seems to work ok for burning CD's from the desktop. Now I just have to see if I can burn a video DVD with it from the output of CloneDVD. EDITED: I can't get DeepBurner to burn a DVD. The free version is supposed to burn an ISO to DVD, but when the process appears to have completed successfully, the DVD is still BLANK . I'll look into this more.
