I'm posting this here and in the PC forum. I am a PC user but am trying to create a DVD (straight data DVD, just images backup no spaning disks or creating multi disk project) for a MAC user. 2 attempts, 2 failures. Both were done with Roxio version 9xe Both done on Maxell DVD+R media The first was done with file system: UDF102 (probably with Joliet Bridge) Second was done with file system: ISO9660 He is getting cyclic redundancy errors and can not copy some of the files or will copy then but their size will be 0kb Also the only files on the disk that seem to be a problem are the larger files, specifically the full size Fuji RAW files. They are all over 25mb. A compressed Fuji RAW file (Fuji has a utility to compress the files that gives you something I believe is like compress NEF), a DNG converted file, Nikon NEF's, and Jpegs copy fine. All the other files are under 14mb. Any ideas?
