I've never seen this before, so I assume it's a 10.0.8.1 issue. Although DVDFab said it was going to compress to 77%, it checked the blank (Verbatim 95079), decided it was ever so slightly too small, and then failed by writing nothing. When looking at other log entries, it appears that sometimes it judged the blank's capacity as 4488 MB and others as 4489 MB (even though they're all the same manufacturer and lot). Any idea what's going on? This has happened at least one other time, too, I believe.
