I have an LG WH?? Blu-Ray Burner and I've used Optical Quantum 25GB 4X BD-R Blu-ray Disc's for about 3 years without issue. (previous Burner was Sony).
All I do know, is that Ritex disks are crap. Cheap and non-dependable. Check out Newegg... They typically sell the Optical Quantium for 26.99 for 25 pk, but if you watch, they will have them on sale for 16.99....
