i was using maxell then i switched to memorex. but i got a bad batch the last time i used them and i switched to sony. i know imation is a low grade disc but i figured i could use them for test runs untill i figure this out. the burner does burn +R's and i have to different players i tried them on and i know they play just about anything. right now im trying to figure out how to use vso inspector to see if this finds anything wrong with my disc. does vso really help or am i wasting my time with it?
