Dvdinfopro scan good?

[The Stinger]

Here is my latest scan from DVDinfopro. Can anyone tell me how to read this? Is this a good test or bad? How do I tell?

[FulciLives]

That is NOT good at all!

You might want to try NERO CD SPEED TEST because I feel (based on my own experiences) that it might be a bit more accurate.

Also I have a bit of a slow computer and I think that can sometimes affect these RPM SPEED TESTS even when the DVD is a perfectly fine A+ burn.

For instance my results with NERO CD SPEED TEST are better than what I get with DVDInfoPro (using the same hardware and disc) which leads me to believe that DVDInfoPro must be more of a system hog on resources.

But still that is a pretty bad looking scan ... and for Taiyo Yuden DVD-R media?

Something ain't right!

Yeah. Download the latest version of CD-DVDSpeed from:

http://www.cdspeed2000.com/

and post your results.

Ok, I got Nero CD DVD speed and this is the result. I hope I did it right cause I didn't see anywhere on there a cd speed test. Anyway, here it is....

[Baldrick]

it is called nero cd dvd speed....(just so my autotool link works...)

Can anyone tell me if my new scan is any better?

Here is a scan I made of a DVD that played back without any problems.



I think graphs that look like mine and yours are ideal but still by no means a guarantee of perfection.

Here is a scan I did using a Taiyo Yuden 8x DVD-R bought from RIMA.COM

This was burned at 4x on a NEC ND-1300A
My computer is a P3 650Mhz with 256MB RAM and running WinXP Pro SP1

First here is the media code from DVDInfoPro



Here is the image of the RPM TEST using Nero CD DVD SPEED (version 3.50)



This is how a good test should look EXCPET the lines should be straight without any dips. I get dips I think in mine because my computer is so slow.

DVDInfoPro gives erratic results for me which again I think is related to the speed (or lack) of my computer.

I should mention that the media from my scan is Maxell MXLRG02 4x DVD-R.

I believe those little dips were from me using the computer while scanning because I scanned again while eating dinner (away from the computer )and the green line was completely straight. I will do a scan now of a bad but readable disc to try and give you an idea.

And because the 1300 is shetty at reading discs. I have a 1300 and I used to do all of my testing of my discs by doing transfer rates using it. Some of my discs with severe dips on my 1300 have perfect transfer rate tests on my newer drives that I've since gotten.

Or maybe if you had used a DVD+R you wouldn't have the dips .

Well I've made a lot of DVD-R burns with this burner that have been played on a variety of DVD players and never once had somone say they had issues.

So yeah it's a GREAT burner ... we have all heard that ... but I too have heard it ain't the greatest reader ... but then again I've seen people use theirs for these tests and get a "perfect" test so that's why I just think it's a speed thing since my computer is slow ass hehehe

Either way I ain't worried about the scans. I know my burns are good

Even the 3500 isn't the greatest reader. I have to use the $9 Toshiba to read discs sometimes because the NEC chokes on them, burns like hell though.

The Toshiba 5112? I have this drive, and it is probably the best reader of any dvd drive I have, and I have at least 6 .

Fulcilives, I agree the 1300 is a great burner. It's my oldest burner of my 4, and yet I know I can count on a good burn from it, whereas the other 3 all have their downfalls. Pathetic, really, that my oldest burner is the most trustworthy (My Benq 822 makes awesome +R burns, but has yet to make a single -R that WASN'T a coaster )

[samijubal]

The 5112, that would be the one. When the NEC 3500 gets part way through a disc and chokes, I stick it in the Toshiba and it reads it no problem.

As promised, I have done some scans. Unfortunatly, all my DVDRs either scan well, or come out unreadable and damaged. I usually throw away my coasters anyway. So here are some scans of data CDs:


This is a Taiyo Yuden CD-R burned at 4x! I am starting to think that these Taiyo Yuden CD-Rs I got from RIMA are garbage. I have never seen so many discs fail Nero verification even at low burn speeds. I have tested them to be problematic too; an MP3CD I made had a messed up song.

In comparison, here is a scan of a Fujifilm branded CD-R burned at 16x with with media code Prodisc. This is pretty shitty media too but this scan came out ok it seems:


I realize the discs used different write strategies and I am trying to figure out why but I don't think a P-CAV disc should look like that anyway.
