BENQ 1620 speed issue

Ok first off let me say I am not very knowlegable about dvds in general (formats etc…).

My issue is this. My sister rescently purchased a benq 1620 and I tried burning/creating image of a dvd of hers using nero 6 and Easy media creator 7.

The image was succesful (usign both programs) and the burn was succesful on (twice on both programs). I tried burning by selecting higher speeds, however, the speed seemed to only be 1x (I believe anyway, 1500-1600 kb/s). I believe this drive is capable of faster speed, so I weould appreciate any suggestion as to what the problem might be.

Thanks

First thing I would do is check in Device Manager to see what mode your device is running in. You want Ultra DMA mode, not PIO.

What media are you using? At 1x that means it took about an hour to burn.

Does the Benq 1620 even support burning at 1x? I have some really cheap, really bad media here (Sony bought from Fry’s), and I was trying the other night to burn one on my Benq 1620, and Nero wouldn’t allow any speed but 2x.

Its in DMA mode.

I believe it was a 4x DVD+R (not sure of brand don’t have them on hand), and yes it took about 45 minutes I believe (3.8x gb data).

Well i’m not sure what it supports or not, but whatever speed I chose it burned at 1500-1600 kb/s (which is 1x I believe). When I was making an image of the original dvd I was getitng the same transfer rate too.

B.u.m.p

try different media

Sound like a DMA issue to me.

Could be IDE driver issue too.

Do you have an nvidia :Z nforce chipset for eksample? If so - uninstall the driver for it and use MS IDE drivers included with the OS.

Try download CD-DVD Speed or DVDInfoPro and read the media code and tell us what it is.

Not sure if this is what you are asking for Hef.

Here is the complete media information from the program. The perticular CD in there is a copy of the dvd which I created the image from and had a slow speed.

Also, My CDROm and DVD drive may be on a 40 IDE cable (not sure, is there a way to check that in control panel somehow?), not sure if this could cause such problems.

So it seems like a no name brand. I wonder what other people think of this media.

junk media the drive probably wrote it in 2.4x those drives will not write in 1x it is impossible.

Buy name brand media such as Fuji, Ridata, Verbatim.

Ok guys. I just set up the DVD drive as master on the IDE cable on its own, and my results improved.

The media I used was a General DVD+R 1x-4x. Media info below.

The DVD burned at 4x 5,540 kb/s (disc speed limit) and Total time was 21 min, certainly an improvement over 50.

I am going to try to get my hands on a couple 16x dvds to see if this was inded the source of the problem. What types of discs would you recommend based on your experience. Finally, do you think buying an 80 cable would remedy htis problem and allow for the DVD to be hooked up on teh same cable as my CDROM.

Thanks.

PS - Yes the media was probably junk, but would that explain getting crappy reading speeds, ie making an image from the DVD.

21 minutes for that amount of data is still 2.4x. Yes,the 80 cable should be used. Nero will say whatever speed you choose it is burning at (4X) even if it is burning at 1x unless you do a registry hack to show real time speed.
That brand is probably not in the firmware so it is burning at the slowest speed for safety sake.

As far as media brands there are about 8000 posts here with burns on different media so just look around and you’ll be able to answer your own question.

Well hopefully I can get my hands on some better media tomorrow or friday to test this further. I really hope this is the source of the problem as it has been a pain in the neck.

Just burned a 700mb image to a CD-R in 2:57, previous to the change it took aobut 15-20 (might have been CD to CD though) I believe. Its looking promising. Ill let you guys know how it goes with better DVD media once I grab some. Thanks.

Have you flashed your drive with the latest firmware B7M9 (if you have Nvidia drivers this will fix that)? You could then download the latest CD Speed or DVDinfopro (the one posted last night) and do a quality scan PI/PIF/jitter just to see how that no name brand looks.

You could try Fuji, Taiyo Yuden (at rima.com), Prodisc, Verbatim, or Ridata (newegg has 100 4x + for $30) even TDK or Memorex.

Some people are buying 4 of these (for free shipping) basically getting a 100pk for $32. Velocity itself is not a recognize brand name, but it’s rebadge MCC 03 (Verbatim) or Prodisc R03 which is.

Someone thing that YUDEN000T01 (Taiyo Yuden) is about the consistently best. Like in this Samsung. One person reported it burned at 12x in the BenG Dw1620.

This TY02 is know to burn at 16x.

just make sure it’s + media.
