This is subhasis from india. Very recently i purchased 2 spindle verabtim 2.4x DL DVD+R(MID:- MKM 001 000 00h) from chicago. I'm using Optiarc 7260s F/W 1.03. Already burnt few in 2.4X speed wth no problem. First Of all my question i'm getting too much PI Error in total And too much of PI failure though the quality score is showing 96. Is it a good burn? The disc was scanned by selecting 8 ECC levels. Need ur suggestion guys.
