Should I keep using these discs?
I've successfully backed up my copy Persona 3 FES before but I had little trouble playing through the whole game. The discs I'd used previously were a 50 stack of Gigaware DVD-R's from Radioshack (20.00 USD). The problems I did have were with the cutscenes, sometimes they played well but other times you'd have to skip them to get to the real gameplay of the game which always worked flawless.
Are these DVD-R's good in general to keep using?
If I were to get Verbatim DVD-R's does it matter if I get this one;
Or this one:
Does it matter if it's 8x or 16x or if it's 4.7GB?
