MicroCenter, online or B&M, has Philips 8X media, both Dvd-R and DVD+R for the same price of $19.50 for a 50 piece spindle.
I thought that was decent so I picked up a couple. I burned one last night at 8X my LitenOn with no problem. "My Cousin Vinny" works just great.
I can't give any further info since I don't know how to do that quite yet
