I have a blu-ray burner but haven't installed it yet. Wondering if anyone has burned to blu-ray here. The discs are still a bit expensive (definitely not DVD priced) and I'm finding that while larger, they may not hold all of my files in one shot (to keep things organized, such as my digital scrapbooking files). Is there a high risk of discs failing like DVD/CDs had? I don't want to burn a disc only to have it useless since they are expensive.
