I had the same problem with the burn error "failed to burn" (after all 180 photos processed) and was happy to find this thread. The fix for me was what kokyu suggested, and the simplest one. I had used the return key in my title. All I did was re-type the title in the edit pane (letting it wrap the way it wanted to as the poster explained) save, done, and then burn. No problems after that. I didn't have to uninstall/reinstall photoshow.
