#1 Comparision of scans from QPxTool and DVDInfo von LSM 18.04.2007 22:21

I'm happy to see a Linux application for testing DVDs etc. I've had some problems with a bad batch of DVDs and am scanning a bunch of my archived disks to check on their condition. I've been using DVDinfo and, since finding it, QPXtool. However, I get quite different results on the quality of the scanned disks. I have matched QPxTools and DVDInfo scans from my Pioneer DVR-111 for a "good" disk and a "poor" disk. In both cases the QPxtools results indicate much poorer quality for these TYGO2 disks. In fact the QPXtools results suggest that both disks are "poor".

I'd attach the scan results but this does not appear to be possible. I'd be happy to e-mail the png files if anyone would like to see them.

Is there any explanation for the major differences in results, with QPxtools apparently finding many more (i.e. about 5-10x higher) errors?

You need some webspace to put the images to. Then you can use the img-tag to insert the scan results in your post. If you have no own webspace, you can use free webspace like rapid share or netupload.de.

I made a big compare session a few months ago with all my Plextor drives and compared QPxTool, pxcontrol and pxscan. And the results were similar.

In your case some graphic would be useful.

OK. Here goes a try to upload images.

"Poor" disk (poor PIE peak at end)



"Good" disk




In both cases both the PIE and PIF lines are much higher in the QPXtools output

strange results, but... DVDinfoPro doesn't show realistic results on Pio111 and Pio111 scan functions in qpxtool are not final now...
thanks for screenshots:)

Let me know if I can conduct any other scans or provide you with some help in resolving this.

Cheers!

now I have access to ASUS 1608P3S that is Pio111 inside, so I'll compare results with Plextor and fix this soon...
please be patient
