#1

The First set of results was tested on a BenQ and was written with the same BenQ:

These were Written with a Pioneer 107-D and tested with the BenQ Writer:

I got recomended the BenQ by people on here.
Isit me or are the BenQ results worse?
I’m hoping they’d be better.
Is there not a speed to burn the DVD’s at or something to make the results better?

@jason69uk. Those look like decent results. Try setting your scan speed to 8x on the BenQ.(pretty much a standard here at CDF) The BenQ1620 burns YUDEN000 T02 best @ 8x or 12x. IMO :slight_smile:


#3

sorted then - thanks v much!!


#4

You are getting results that I would expect from both burners.


#5

I have just done an 8X burn.
Whats all the jitter about at the end does this look normal for a DVD+R burned at 8X on a BenQ 1620 Writer?

At the start of the burn the Drive loading light was flashing green and porange then went and stayed on flashing orange thru out the whole burn?

Please, is all this normal??
Isit also normal to get a bad start to the burn shown on the transfer rate graph of every dvd i burn with the BenQ?
It’s 8 Speeded TY Media.

Cheers ppl.

The shaky yellow line is nothing to be worried about. The shakiness is just some math roundoff whatnot that you don’t need to care about. A nice, smooth curve on the green line is what you want, and it’s what you got. You’ll see some pretty dramatic stuff on one of those if you’ve got a bad burn.


#7

Ooh right so its the green line im focusing on then?
Just done on at 12x and had a little rise in the green line just about 2 mm.
This is normal though yeah?
I ignore the yellow line?

I have attached some images, the first image is the graph when a TY DVD was burned at 4x on the Benq writer then at 4x on the pioneer (Thats the 2nd pic)
How come the burn was better on the pioneer when BenQ are meant to be the best?




#8

ne1 know why its like this then?
please look at the first graph comparing with the bottom one and tell me if its normal for a BenQ to write a bit worse than the pioneer?

I think idefinatly got a problem here though.
A feature on CD/DVD speed is called Scan Disk.
I do a surface scan and the first block is red which is unreadable.
Does this to every disc written on the BenQ.
Also on the transfer rate test the lines go up really quick then straight.
So it seems the start of the burn is not a good one.
How do i sort this?

Cheers.

nebody, no…?


#10

Run the PI/PIF tests on the media and post that.


#11

Boy, you’re really splitting hairs here.

They’re fine. Nice, smooth curves.


#12

You’re allowed to worry about quality when you get scans like this (or worse, ones that don’t finish):

(Thx Pioneer DVR-109 review!)

Until then, you’re fine.


#13

All I see you posting are transfer rate tests. Run some disk quality tests and post.


#14

This was written @ 12X.

Don’t you have to more or less fill the DVD to get an accurate pie/pif test ?? I thought that the worst point normally on the DVD was towards the 4GB mark.


#16

Hey Jason… Sideswipe is correct although you can get some ugly errors at the beginning of a disk also. You do need to do a full burn to get a proper reading. With Nero, you can do create data at 8X then do a Disk Quality test. This will give you a full burn and test to see exactly where you stand.

Wheres the option to create data at 8x?
This one here was burned at 8X and is data and the DVD is almost full.
Thanks for all your help by the way.

Hey jason… This is a fine burn. I’d take a 98% score any day. But you aren’t quite full. But in this case I’m not sure it would matter much as your very close to full. To do a creat data disc, open Nero (or CD-DVD Speed). Go to file and then options. Under Std. Tests you can set your read and write speeds. Set to 16X read and 8X write NOT MAX!! Under Transfer Rate, check Data or show Data,(this will show your write speed in the test) Read Test and Write Test. Here set your max speeds to 2 over their limits. Always save your files as png. type. Under Run Test, you have the option to run any or all tests. Last one (F9) is Create Data Disc. This is what your looking for and what you need to do first with a blank disc. Then under Extra you have your Disc Quality Test which it looks like you’ve found. And thats it. Now lets se what you’ve got.
