Of the now hundreds of DVD-Rs I've burned, I've NEVER had one melt before. To my surprise the dye on two of my Vakoss 8x DVD-Rs is literally running off the disc! At first i thought I had exposed them to heat or direct sunlight. But no, they were in storage in a cupboard. The only one factor that may of caused it was that they were both played in my friends modded PS2 a day earlier. Up until then they were in storage for three months with no apparent defects. Very odd. Has anyone had this happen before?
