I just wondered what make and model your Burner is???
Have you checked with the Support line for the Burner??
I did right after I purchased mine, BenQ External Burner and the Support Line was extremely helpful. They told me the brands of media to use and as well that I should burn in "DVD ROM" so that the backups will be more useable on the diverse players that I use as they are various models and vintages!!
The Support also advised me to use R+ only for my Burner and then recommended specifice Brands that BenQ said the burner performed at its optimum with. I followed what they advised and have had no problems and I am indeed a Noob to all of this Burning!!!!
Just wondered if you had an opportunity to do this as I found it extremely helpful !!! Just thought that I would pass this along as being a Noob, I know how frustrating it is getting started out.
