maraming salamat sa mga replies.
i use two writers, liteon and asus. sa liteon, defective ang burn nya kapag may skip yung burn nya, yung may line along the disc. sa asus yung may cloud-like image.
and i check the discs, wala naman syang visible defects, bago ako magburn. before, i tried using P25 discs, 3 out 4 ang unsuccessful burns. that's the reason kung bakit cheapest ang kinukuha ko. kung unsuccessful man, hindi masyado mabigat sa loob. ehehehe. nagstart itong pag iwas ko sa expensive blanks noong panahon pa ng CDRs. mapa verbatim or philips, pareho lang ang success and failed burn rate sa P5 blank generic CDRs.
regarding sa firmware, hindi pa ako nag attempt mag upgrade. 1st, kasi successful naman sya sa TOP-DVD-R and Gold discs ng CDRKing, and not all of the blue discs i bought have unsuccessful burns. more than 50% ang success rate nya. 2nd, baka magkamali ako ng upgrade, hindi ko na mabalikan yung orig.
btw, i've read here that we should burn on a slowest speed whenever we use generic discs with more than 4G of space. sa experience ko, kapag naaasar or nagmamadali ako, i will use 4x. pareho lang ng success/unsuccessful burns with 2x or 1x.
