i burned the same iso before with imgburn, also latest version, and i could only see it in disc channel. After that i get read error. The iso i burned with UltraIso is exactly the same. But the one burned with UltraIso works perfect.
I use tsst-corp laptop crap burner with Platinum DVD-R 16X. I burn at 3X. Works perfect.
I also use this burner with Platinum DVD+R DL for my Xbox360 games and also never had problems with it.
P.S. When i used IMGBurn to burn Mario Kart i changed the Layerbreak settings back to Calculate Automatic.
Good to see you guys are up and going.:)
