I just wanted to let jdobbs know that I got a 0004 error on rebuilding this morning using .60b. I don't know how valid this is, as my source was a Video_TS folder authored by DVD-Lab, and I let Rebuilder use my old Rebuilder.ini file. I opened up Rebuilder .59 and just clicked on rebuild, and it finished fine. Like I said, I don't know if this is even a valid problem, but if you want more information, I'll post version #'s of CCE and such when I get home this evening.
