princo dvdr r good as long as laser is good
if u suspect your lase to b bit old v4 or older i recommend u use traxdata or white label (both gen 3) 100% working rate even on v3 with real shit laser
traxdat £1.09 disk white label 0.89p
if u got v5 or newer chioces 2x media @£1.09 is cheap and fast to write
problem i had with princo and ao4 was with princo cdr
this since been fixed i think it was just 1 batch
next batch my m8 bought()he has use them his standalone sony wont read cdr
but it will read princo cdr
xbox not read cdr pop princo in it reads
(because of this fact princo r being taken to court and its illegal to sell princo cdr in uk at moment
princo cdr and dvdr works fine in the ao4
