I'm trying to burn a mix of mp4 and avi files with Roxio Toast Titanium 9 as a data cd. The blank DVDs I'm trying to use are RiData, 8x DVD-R, with 4.7 GB of free space. Each of the files I am trying to burn is about 350 MB. The problem is that the space remaining always shows up as zero bytes, and Toast shows that it will span something crazy like 400 discs. I've tried different blank DVDs, and also opened them to see if I accidentally tried with a DVD that was already burned, but they're blank. I also tried trashing the preferences file. No joy. I'm new to Mac (this Mini is my first), so I may be overlooking something pretty basic.
