I have ordered hundreds of products from Amazon and cannot remember one that I returned...until now.I am simply interested in finding some re-writable discs to use with my DVR...nothing special.I thought that this was the product because the Manufacturer stated on Amazon that this is "the perfect medium for recording home movies and other video-intensive activities. Compatible with DVD+R DL drives from Sony, Philips, Lite On and other leading manufacturers."Once I received the product, notes on the package implied that additional firmware may need to be downloaded to make these discs work.I am returning the product because these discs do not work on their own with my DVR. I strongly suggest that Amazon insist on more objectivity and much less hype from the manufacturer regarding the online product descriptions.
