I've just wasted an expensive DVD+R dual layer thanks to some bugs in the burning program. My laptop could handle the burning fine (hopefully) but I couldn't read the source DVD because of the crappy quality of the DVD reader inside (I had the same exact problem with my old laptop), and on my desktop (MDV 2006.0) k3b refuses to burn, and growisofs borks mid-way with a generic error, in any case the DVD is wasted, bah. Next time I'll just move the ISO over to my laptop....
