Just tried out these HP DVDR+ 8X discs I got from Officemax. For some reason my computer won't mount these discs anymore. It did last night and now it doesn't read them. My computer can read any other discs.
What gives?
That's a situation with the Mac and MacOS software. DVD+R may not always work properly and, until very recently, has not been well supported on the Mac. Best bet is with DVD-R, which you should be confident will always work.
