Ok, this seems to be a commonly asked question but no one seems to address it directly. We all know one of the cheaper dvd-r media brands is princo. And most of us know that using a cheap dvd-r will damage your laser, and replacements are pretty expensive. So the real question is, will princo's damage your laser, or are they safe? Everyone's comments are welcome. Also if anyone has experience with a damaged laser please post the problem and what media you were using. Thanks!
