These are TYG11 Taiyo Yuden manufactured discs that I've seen people online asking about, branded by JVC, of course. I've had zero problems burning these in Imgburn - the program sets the layer break on them automatically. I haven't tested them with any other program. When used for video, they play in my PS3 and Toshiba DVD Players beautifully. Definitely buy these discs if you want Dual Layer. If you need a +R disc, obviously stay away, but that's about the only reason I wouldn't buy these.
