I basically found out the hard way that not all media are created equal, so i figured i'd ask what things there are to consider when buying media. 1. I just found out about the media compatibility with the brand of burner that you have. 2. What are the differences between the dyes, i read about organic dyes, azo, metal azo, super azo, super sensitive dyes? whats the difference, and is ther any one that is better than the others. 3. Which is the media that has that really cool purple looking back, like the one on some ps2 disc, sorry just couldn't resist asking, and is it any good.
