New Toy: DVDScan and Feedback Here:

A first test - Staples brand CMC E01 8x in Benq 1640 BSLB SB off WOPC on -

P.S. - I resized to 75% and it seems to be a perfect size to scale down to for the forum, at least at my monitor's resolution. Lower resolution and all bets are off .

Here's a BenQ scan of a Prodisc-made Verbatim 16x burnt on the Lite-On. Will post the DVDScan screenie of the same in the next post.

4x jitter scan of the same Prodisc-made Verbatim 16x, burnt with the Lite-On 165P6S.

P.S.: another option to resizing the screenshot is to resize the window so all the blank beige areas are removed.

You can change the interval value to shorten the testing time.
I usually change it to 0x8000.
The interval value is not used for PI/PIF scan at this version, next version will be.
USB/Multi drives supporting has problems and Tom is working out. I think there would be soon a new version for you.
Thank you for all the great testing and feedback. Thanks.

Sorry, EI_Mariachi_X, I am still thinking of you suggestion without conclusion. So I apologize if it make you feel not good. By the way, the results of your scan seem OK for me.

- have no idea what it all means yet (re-reading tech specs)

Hi bichi

the screenshot is of the jitter test, not beta. As long as the stays under the orange-red line at 110, things are quite good. Very nice scan, BTW.

alexanderino,
- thanks for your feedback!
- yes, I know what jitter is, but not quite sure how to interpret the graphs
- I put "beta" in as part of the application version, not that I was trying to run a "beta" scan.....

Many thanks to Wind, Tom, Karr, CodeKing and the rest of ya'll, for bringing LiteOne back into the limelight!

you're right, my brain is borked at the moment

As for jitter, a nice explanation can be found here:

Jitter expresses how much the structures recorded to a disc deviate from the length they are supposed to have. Jitter should be as low as possible...

In other words, it examines how evenly sized the pits and lands are. The more the deviation, the higher the jitter percentage

Preliminary scans show that Lite-On reports higher jitter than BenQ.

As what I understood, 0% (-5% to +15%) should be refer to Asymmetry, Beta is about 2 times of Asymmetry.

Hey my friend, thank you for your clearly feed back. I think that's what Tom exactly want. And I think he would implement these items as soon as he can.

Thank you and Tom for sharing this lovely "toy" Can't wait for the next release!

To me, that's an excellent result!

You can change the orange-red line by yourself, just modify the jitter spec. value. I think if the jitter value is under 11% measured by 165p6s I think that would be OK. So I asked Tom to set the initial value to 110. Of cause you can change to what ever you want, that's just for reference only. Sometimes, even the jitter value is slightly higher than 110, the pi/pif results are still good. Everything is for reference only. No big deal.

Hi Wind, with my 1635S and the latest test firmware works only PI/PIF test.
It's normal?
Thanks a lot for your (and Tom) work.

What's your test firmware version? It shall be able to measure jitter, or I have to check this with our engineer.(Oh, No! Today is Saturday!)

I have the last test version, YV6M.
Don't worry, I'll wait for next week.
Thanks.

I compared jitter tests at each speed and the results at 6x and 8x seem alot more erratic vs. the 4, 2, and 1x tests, the three slower speeds follow a much closer trend (probably related to the fact that 1-4x is CLV and 6x and 8x are CLV). IMO, for this reason I would tend to stick with 4x for jitter testing. This is with a 160P6S, whether this trend also relates to the 5S series of drives, I don't know.

Benq 1640 scan for reference, followed by 1x, 4x, 6x, and 8x in the Liteon 160P6S. Disc is a Memorex Ritek R03, burned at 8x in Liteon 160P6S PV8Q, SB HT OHT all on.

dvdscan doesnt see me 1653s sorry i cant help in testing maybe there might be a fix in future release's

Another observation, looks like the PI/PIF testing may still have some bugs to work out. This is a PI/PIF test of the disc in my previous post, you can see the two random error spikes in the scan. I was multitasking, maybe it was a one-time random reporting of errors, but I don't think they are being accurately reported. I'll run a test with CD-DVD Speed to see what it reports in the Liteon (the Benq scan is in the previous post). edit: Just to confirm, I just ran a test in CD-DVD Speed and the error spikes aren't present. BTW, the block of errors reported up to 4 PIF in the CD-DVD Speed test below are from a large speck of dust, disregard that (the block of errors can also be seen if looking closely at the DVDScan test).

Did you go into your control panel/device manager and disable all of your other optical drives as well as any virtual drives that may be listed? If not, you will need to do so to run the program properly at this time.

scoobiedoobie and jacen9, don't think this app supports "3" series drives...

Thanks to all that made this tool and members involved with testing.
It's always better to have more (then one) tool for jitter testing.

Whoops, at first glance I read it as a 1635, not 1653.
