I meant to add later that there's such a variance between burners that I honestly don't know which one to believe anymore. When a 1640-burned disc is scanned (with PXScan/Plextools) in my Plextor PX712a, the results are quite different than the scan above. Good, but not as good as above. Yet, when I burn this disc in my Plex the 1640 shows horrible scans in CDSpeed while the Plex shows it to be a pretty good burn.

I'm not sure if I trust the 1640/CDSpeed combo with scanning CDs. I have a CDR with known "slow" sectors; every app (including file copying in Win Explorer) slows right down when reading the files in the affected area. Yet the scan on the 1640 looks perfect, and there's not even any dips in the Read Transfer test. The Plex, OTOH, correctly shows C2 spikes in that area and a slight dip in the read transfer graph.

I'm guessing that the difference is that the CDSpeed/1640 "samples" the disc whereas the Plextor reads everything on it. That would certainly explain how & why the C1 scan takes a significantly shorter time than CDSpeed's "scandisc" function (which, BTW, shows yellow for the aforementioned "slow" areas on that disc). It would also explain what crossg has noticed in DVD scanning: take the disc out, put it back in, re-scan. and you get better (or worse) QS scores.

This suggestion is for both BenQ 1640 and Prolific engineers. Please make these two compatible so that a wonderful drive can be used in the best possible enclosure

Include an option to turn off WOPC. Either a command line option in Qsuite or something in the firmware.

I assume you mean switching WOPC off permanently? You can already switch it off temporarily you know...

How about updating the help file in Qsuite that explains Solid Burn and OverSpeed tabbed functions.Your help file makes no mention that they even exist.

It would be nice to know how to use these features from BenQ's point of view instead of having to search the Internet to find out how to use them.

I submitted a request to your tech support department for a FAQ or instructions and they asked me to call the 800 telephone for information.

Even your latest version 2.1 does not have any information in the help file

Solve the problem with CD-RW for both BenQ 1620 & 1640!!!!!!!!!!!

Please fix QSuite 2.1, with the bug that causes it to lock up during a FE/TE QScan when "Overspeed" is selected and a DVD+R media is inserted to test at either 12x or 16x. See here for details.

See next post (here) for additional details. The FE/TE testing at 8x (no overspeed) is also freezing on me on QSuite 2.1

I don't know if this has been covered yet or not.
Engineers please look into the 16x burn issue with Benq drives within some setups. For a lot of us our drives, 1620 and 1640 will not reach 16x with any media used. My 1640 was only able to finally reach above 13x after using the external version of its firmware. Most likely because of the mode 4.

Consider giving the user a BenQ 1640 overspeed firmware (non Solidurn/Overspeed), like the BenQ 1620 Firmware (for good media like YUDEN000 T01,T02, MCC 003 MCC 02RG20,TYG01 and TYG02 ect.) Give the end user a choice to use either a FW with Solid burn/Overspeed or a Overspeed stock FW without Solidburn/Overspeed.

- Enable/Disable SB and/or WOPC on a per media code base.

- Support UDMA3/4 in fw for internal drives, so they would work better in external cases…

- Why not having unified fw for internal/external versions? It is pain for Philips to maintain two separate forks while it is pain for us to cross flash…

Have a native English speaker vet/produce English language documentation, and any use of English on screen forms in Qsuite. The existing translated versions are of low quality.

Can you please keep the firmware of the EW164B up to date with the 1640 firmware?

Indeed this bugs me as well, my BenQ 1640 is slave and QSuite 2.1 too dumb too look for the device.

What about a stable SB not this beta sh**.

How about user defined riplock, include the QSuite option, for the permanent settings control?

please do something about the cd and cd-rw write quality for the dw 1640.

For me, nothing wrong with it - Nero shows me a score of 97%

Partly will possible comply with this. But only about Ultra Speed RW recording.
Burning at 16x is awful at 24x is extremely deviated, at 32x more or less but acceptable. CD-R recording is near to perfect with the exclusion of too high level of jitter.

To be honest I dont really care about CD-R/RW issues on this drive as I bought it as dedicated DVD. I have a plex Premium for that.
But I do understand there are people out there that do not have this luxury of having a dedicated CD-RW drive.

As for the drive I just bought (SONY DRU-810A) flashed to BSLB BenQ I just burnt my first cheap disk (memorex branded x4 DVD-R with ProDiscS03 mid)
and overspead to 8x and got a decent score of 97 w/ 10.2 max jitter.
Now this media overspead in any of the other dvd drives I own fails and even @4x in my other drives results are as good as the 1640@ 8x

Now I know the only diff between the sony and benQ 1640 is the ESMT(Elite Semiconductor Memory Technology)buffer mem chips it uses but I wonder if anyone else that is out there have a sony/BenQ drive and think it could have better QC? At least im hoping it does.

I'm certain that it's already been requested many times already, but once again: Give us more flexibility in Solidburn, as in ability to delete each SB media code profile individually, the possibility for more than 6 profiles, etc.

I'll second that on the ability to remove individual learned pieces of media..
If you get a bad learn you have to remove profiles that learned correctly.

Maybe an X type button(like the one to close open windows) next to each slot to delete a single piece would work out nice.

Hello, to Philips Engineers, and also to any cdfreaks who might be able to provide any helpful suggestions. = I recently purchased a Philips DVD+RW DVD8701 burner, which I am very pleased with in every way, but evidently I purchased it too hastefully, because I forgot to check if it has the cd-text feature, which appears to be unavailable. . . This is a silly question from a rather inexperienced pc user, but is there any way possible that the cd-text feature could be made available to this cd burner ? Thanks !

Make solidburn work better - I have issues with solidburn where the first burn using solidburn is good - then the following burns experience issues where the jitter seems to start going bowlshaped and I get a block of PIF's where the speed switches from CAV -> CLV at 8x. See the scans attached. The first scan was the first burn, and the second one is what the subseqent discs all look like - notice the block of PIF's at a level of 6 ..... looks concerning.
