So yesterday-----At Office Depot, they were selling 50 pack DVD-R and DVD+R. In a rush to buy monitor cleaner-----I grabbed DVD+R.....Now, I know this may be an age old question----and after a test the DVD+R do work for me, but I'd like a general consensus on which is more compatible----I have a Sony player--and it works for that-but I'm worried about friends and family who might have diffrent players-
