I am trying to burn a TechTool Pro DVD that I purchased in connection with the current MacUpdate promo package deal. I have tried burning the image with Toast Titanium 8 with Tiger (OS X 10.4.10), but when verifying the DVD, an error appears about a "bad sector". I have earlier tried to burn DVDs with Liquid CD, with similar results. I have yet to burn a successful DVD, but have no problems burning CDs on my G5 single (PPC). The TechTool Pro DVD loads fine in the Finder, so I am sure that the download functioned properly and that I have the full image file. Soooooo does anyone know what to do to solve this problem?? Cheers, Brian
