ive bought both the benq 1620 + liteon 1693s [btw. thnx for all the help.]
but now im totally lost as regards to the burn quality/scans, as both drives
give diffrent results! i think, the 1620 scans once every 8 ecc blocks and
the 1693 scans every single ecc block [correct me if im wrong.] scans on the
1620, irrespective 4x or 8x, gives extremely consistent scans, the pif's are
off only by a dozen or so. but the 1693 is totally inconsistent at 8x, heck
even @ 6x the scans are way off compared to the 4x scans. im not sure what
to make of it, im totally condused here, i just cant seem to find any
correlation between the scans of the benq/liteon drive, even of the same media!
[the benq can however show jitter plus poe/pof but cant read c2 errors,
which is helpful in the scandisc in nero cd-dvd speed, while the liteon
can do pie/pif and c1/c2 but cant do jitter or poe/pof, right?]
the 1620 seems to be better @ reading bad dvds than the 1693 [well ive only
done a handful of tests now.] but the 1693 seems way better @ burning cds,
ive already retired my ltr-52327s cd burner as the 1693 burns r better. heck
i even chuckled when the first cd i burned gave a better scan than c0dekings
using a cmc mag cd rather than the prodisc used by c0deking, which in my
experience gives better scans. however repeating the same scan almost an hour
later, same dvds/cds, on the same drive gave quite a diffrent result.
recently ive stocked up on some really nice media, maxell 002 8x +r MIJ,
[well 400 to be exact,] and compared to the riteks ive been using since
i got a dvd burner, g03 4x -r, g05 8x -r, and r04 16x +r, theyre really
really good, no more 50-60 million pies or millions of pifs.] so ill
be burning these for quite a while, therefor i really want to improve the
burning quality for these discs. ive also including the scans i did so far,
both dvds and cds in the 2 previous posts b4 this 1.
ive already flashed the benq with the B7V9-RPC1 and removed the riplock,
didnt fiddle with the booktype management as it seems they were already
set to dvd-rom [im actually quite impressed with the 1620.] as for the
1693s ive flashed it to KS09 and removed the riplock + changed the drive
to rpc1 and also set dvd+r booktype to dvd-rom [not sure if it was changed
for +rw or +r9 tho.] both drives i bought were boxed retail. and both drives
were flashed with the same exe files that the firmware was in. i couldnt
however save the original firmware that the benq came with, dont know of any
benq firmware flashing/backup utility. but ive saved both the original
firmware and the eeprom of the liteon drive. even tho i modified some of
the stuff in the firmwares, like write strategies/speed hacks all have been
reflashed to the above mentioned settings.
note: the liteon 1693 seems to spinup and then down 5 or 6 times when burning
a dvd so it takes longer to begin burning. dont know if this is normal tho!
1 faulty chipset that chas0039 mentioned about the 1620 previously, exactly
what is it? how do i know if the drive i bought has it/what can i do if i find
out that i have this problem? itll be really helpfull if u can answer/atleast
point me to the place/topic where i can learn more, thanx.
2 so the first question is what should i believe regarding the scans? i cant make
any heads/tails out of this thing! even the same drive gives diffrent [esp the benq]
scan results after just an hour or so!
3 how do i improve the write quality of the maxell002 8x dvd+r [MIJ] media on both
the benq and the liteon drives? and especially @12x burns. well i wouldnt mind if i
cant burn @12x on the liteon as long as the quality @8x improves substantially and
also on the benq. [the cd quality seems to be quite good on the liteon and im going
to use that as the primary cd burner.]
the reason for me asking the #3 question is because ive seen very many burns and scans
with the benq that has less than a 1000 pif's, heck even when burned @16x!!! as ull see
from this post [ http://club.cdfreaks.com/showpost.php?p=1052503&postcount=6 ] that even
low quality [well atleast compared to the maxell MIJ's] discs can have really nice burns,
and these were scanned with the benq itself!! the only time i get lower than 1500 pif's
is when i scan with the liteon but not with the benq!
