DC, The logfile is showing that the burner can't read your Verbs, You could buy another single verb or small cake of them and try the burn again, if the same happens, it looks like the drive is on route to heaven. If it should burn alright to the different batch of verbs, then perhaps its a bad batch of verbs your working with ( I've never hit more then 1 bad verb out of a couple hundred before. )Honestly think its your drive starting to die though.
