When I first started burning my 360 backups, I used a bunch of Fuji Film DVD+R DL and Memorex DVD+R DL which I had bought on sale. I bought these before I even got my DL burner, cause I saw them on sale for real cheap.....anyways, sad to say, I ended up with about 30 coasters.
I couldn't figure it out. Once game burned fine, so i assumed it must've been the image.....so I went out my way and bought Verbatims...sure enough, the disc burned fine!....So I thought it was the discs for sure....but then I realized, I was burning the images off a different hard drive - originally was trying to burn the images from an external hard drive....so now I"m not sure if it's the discs or the drive...
Anways, Futureshop here in Canada is having a sale of 15 pack of FujiFilm DVD+R DL discs for 24.95....not bad at all if they work for you.
Only till the 18th or 17th....
