Someone needs to post DEFINITIVELY why -R and +R would or wouldn't work ,while the two of us would have the same machine. Case in point,My brother sent me
'Raidersof The Lost Ark' on a TDK +R,and it stopped at chapter 5,and refused to go any further no matter what I did. but copying it to a Memorex -R,it played beautifully on all 4 of my machines (2 Sony standalones dvp300-s,and NS315-S,my Sony DRU500A on which it was burned,and an ACER DVD-Rom in my daughter's PC)
Go,Figure....and the DVD manufacturers are pushing 'plus' like it's the cure for a plague....
