The 1.0g firmware did include some updates on specific brands of media, but you must understand, that yamaha's techs TESTED this media, and the only way anything would have changed is if the media quality was horrible.
Imation discs have LONG been the WORST discs available on the market....... Perhaps the worst ever made.
I would suggest visiting Yamaha's website, and getting the suggested media, you will have no problems with it. As far as "quality" goes with writing and media, there is NO other writer, that has produced, the quality of this drive.
