I am having a problem that started with the last two betas. The copy process goes fine and the DVDFab switches over to burn the disc, begins the process ( call it preburn, where it it seems to be checking the disc) and then errors out. The errors vary ( 100, 105 & 116). It ejects the disc and then puts up a dialog box saying the burn process failed and if I would like to burn again. Putting a new disc in the drive doesn't change a thing as once you click on yes, DVDFab never starts the burner, it simply times out. The old disc is no longer usable.
This has happened also with 2 different packs of DVDs and is happening after previously burning discs without a problem just before it happens. I am attaching the log file for the last several burns. I must also point out that this a new installation on a new hard drive of both Windows and DVDFab.
