I'm having an extremely frustrating problem. I've got a show that I've burned multiple ways, and I can't come up with a disc that my DVD player will read. I thought I beat this problem when I installed Nero 7. I first had this with an SCI show that I was trying to burn with Sonic Solutions. I used the same approach with Nero, and succeeded. This time I've wasted a small pile of blanks trying to burn a Devildriver show. I followed the above directions perfectly, but now I'm out of options. Should I try a DVD-R instead of a +R? Neither of my burning programs work. Any ideas?
