Suggestions to BenQ and/or Philips Engineers

Don’t know if anyone has noticed this but i just bought and installed a 1655, and i noticed that when you put it in the bay the vent holes on the side are covered up. I think they should be on the top or bottom so you have better cooling. i wonder if this is going to cause over heating?

Many people have cut a hole in their case to expose the vents !!!

Unfortunatley on a lot of cases (including mine) this would mean cutting though the actual rails that you need to screw the drive to. It’s just a poor design element - Benq should have moved the vents towards the back of the drive, instead of exactly where the drive rails go.

i’m sure its been said but it would be nice to have an official firmware that let users write MKM 001 Verbatims at 8x instead of being limited to 2.4x. I have a BenQ1650.

When burning a DL disc (RITEKD01 in particular, pack of 50 Memorex DL discs) the drive will sometimes give a write error as soon as it starts recording the 2nd layer. Out of 4 discs I’ve tried: (all recorded at 2.4x)

(1) BSMB WOPC on: fail
(2) BSOB WOPC on: OK
(3) BSOB WOPC on: fail
(4) BSOB WOPC off: OK

I’ve read somewhere on this forum about successful DL burns being obtained only with WOPC off, it may be the case here, I’d need to try a few more discs to make sure.

Sorry, forgot to mention I’m using a 1640.

With the new firmware BCHC for the DW 1650 I can still write (=destroy) my High Speed CD-RW (rated 10x) at 48x!

its been said again and again, improve/fix 8x burning with MKM 001. looks like this newer firmware hasnt done it.

It doesn’t effect many, I know but why oh why is 2X DVD-R burnt at 2.4X? :doh:

This is surely the reason why all my TDKG02 000000 turn into beer mats. :sad:

How hard can it be to write dash media to spec? :a :eek: :a

This “bug” effects ALL…

But all these facts has been known for years now, although BenQ/Philips has sofar done nothing to it.
4x burning is the lowest safe write speed on any -R/-RW media.

Thanks pinto2.

By [I]“doesn’t effect many”[/I] I was meaning that not many people would have a great deal of 2X dash media they needed to burn. :bigsmile:

A burn using the 1650 @2.4X produces a complete coaster of PIE Max ~600, PIF Max 40 with shocking averages and totals, but crossflashing to Philips 1660 produces perfectly passable burns @ 2.4X! :confused:

Tried every combination of SB OS and WOPC with the BenQ firmware. I thought overspeeding to 4X may work, but the write just failed. Default settings for the Philips (SolidBurn on for all, WOPC locked @ on ( without assistance :wink: and OS off) worked fine!

Probably an issue that has been covered before, but it would be nice for the DW1650 and DW1655 to be able to burn well a greater variety of DVD+R DL media… Right now only Verbatim DL discs seem to produce good results, and as we all know they are still quite expensive. It would be nice to have a firmware that improves burning quality in PHILPS-CD2 and RICOHJPN-D00-01 media. All my burns on such media have been catastrophic so far. Haven’t tried any CMC-MAG-D01 or RITEKD01 media yet, (and most likely won’t as I’m fed up producing expensive DL coasters… :sad: )

As probabaly would have been reiterated by some for many times, apparently no 12X CD-RW could be used on my 1650; only some 4X ‘gold’ CD-RW could survive.

While the CD tray is probably among the best I have seen, the front panel left much to be desired. The eject button feels filmsy make every push a guess; travel of button is so small and non-tactile makes me almost have to re-push on every other use.

The surface texture of the panel is so fine and shiny that makes it looks cheap and toy feel.

Probable the most funny thing is the right most logo on the panel, it actually deepens the exacerbation on its CD-RW compatibilities. And I really dont understand why they choose to put in such a logo and let go of a ‘DVD-R/RW’ logo, this is a DVD drive afterall. The 1670 probably have much improvement in these respects. :slight_smile:

BenQ DW1640 (Tested for BSKB and later firmware)
Read error for 700M CDRW, work perfect for 640M CDRW.
The only way to read 700M CDRW is using dump it as an image and mount by virtual CD manager.

Please fix the scanning dip which always appears around the 137MB mark (DW1650).

Hi, i own/owned many dirves. I have/had 3 LG, 3 Benqs, 4Philips, 2NEC, 1Pioneer, 2 Sony, 1Samsung.

Over the past say 3 years. And for me Benq is the best of them all.
But i would also like them be the fastest of them all. I know you can get fast burns using the Qsuite options but its still not in the speed class of the LG-4163/4167/H10/H20.

So my suggestion is to implement [B][U]8x, 12X AND 16X SPEED P-CAV[/U][/B] into the burners. This will enable them to be as fast as LG and keep the king seat in the overall dirve standings. Obviously the quality will need to improve but this will better the overall perfomance of the drive on slower burns too…


my suggestion is focus on quality not speed using old burn curves.

Ok, here’s a real firmware bug for you. It effects my 1640 and 1655, not sure about earlier models, I didn’t try any.

When burning a simple single track/session ISO, switching SAO (having already sent the Cue Sheet) to TAO doesn’t work, it still uses Cue Sheet values resulting in a ‘End of User Area Encountered on This Track’ error.

Steps to reproduce:

  1. Tell the drive to burn using SAO via the ‘Write Parameters’ mode page.
  2. Send Cue sheet.
  3. Tell the drive to burn using TAO via the ‘Write Parameters’ mode page.
  4. Start writing.

It will fail on the last block of sectors you try to burn (in my case, I burn 32 at a time).

Example of failure:

(Please note, here I am forcing a fall back to TAO after SAO ‘Send Cue Sheet’ fails - again, on purpose)

…and if I remove the call to ‘Send Cue Sheet’, here’s an example of it working as expected:

The BenQ drives are the only ones that have a problem with going SAO -> TAO.

I’ve tested Plextor, Pioneer, NEC, LG, LiteOn and of course BenQ.

How about some damn new solid firmware for all us suckers who bought 1650 and 1655.

current works fine for my needs :stuck_out_tongue:

don’t count on getting any new firmware from either benq or liteon though
i checked a few benq sites last night no link to dvd-rewriter firmware / selection & products still lists 1650 & 1655 but firmware link only has firmware checker
no firmware added to liteon’s site as far as i can tell
always thought liteon would bury the benqs on takeover unless its a website glitch then its happeneing… so much for my 2 year warranty :rolleyes:
