I am not the expert on these errors but to me it looks like your drive doesn't like that DVD+RW, well to be exact the dye that it's using. I have not tried one of these so can't be 100% sure but I am guessing that your drive is failing to write to the disc as part of the format.
You might want to get better quality Verbatim DVD+RW's and see if that sorts the problem I did try and see if there was a firmware update available at www.rpc1.org for your drive but I couldn't find your drive !!
