Hello people, i burnt a sony dvd+r today with my new 7220a (mediatek chipset), misc files from the comp, here's the result.
Drive: Optiarc DVD RW AD-7220A
Disc: DVD+R (SONY D21)
Selected speed: 4 X
PO failures: n/a
Elapsed time: 14:02
Number of samples: 129143
Average scanning interval: 1.09 ECC
Glitches removed: 0
Seems pretty good... but i selected it to burn at 12x (i never trust my comp to burn faster), but what happened was halfway through the burn the speed got throttled to 8.5x :(, and the drive buffer kept fluctuating, why did this happen??
Getting some verbatim dl discs in a few days time see what it does with those.
