Okay hwp... 
Quote:Originally Posted by pinto2- "Refence velocity" = 3,49m/s = 1x DVD speed.One of the first things I learned when joining cdfreaks forum more then 2y back was how to interpret PI/PO scans and I learned it from OC-freak. He posted a nice simple guide here and he also pointed out PI/PO scanning should be done at 1x speed according to ECMA. (Note, he is not quite sure on this point though.)Quote:Originally Posted by hwpNope. It's 2x.
In his guide OC-Freak referes to ECMA-267, the base for all references when dealing with basics for DVD's, testing and messuring of different kinds. Already there it's stated that the reference velocity is 3,49m/s (and the same should apply for jitter testing).
I know it might be confusing when ECMA standars in same line mentions "scanning velocity at -channel bit rate of 26,15625 Mbps- which of course can give the impression of reference velocity equal to 2x DVD (read/write) speed.
But if we look around in ECMA and other publications, a DVD disc speed of 3,49m/s is clearly defined as 1x DVD read speed.
Everyone that would like to get more insight about DVD history, media, testing (also jitter) and common techniques can read this essay published at cdrinfo.com.
BTW, from my own experience, a jitter of 13% (max) is barely acceptable for any longer sections of disc, but spikes at that value really doesn't seem to infect readability.
But for disc longevity reasons I have hard to accept (average) jitter higher than 9-10%. - Posted:

Way off topic
Now I see what might have been confusing you hwp. Sorry not clarifying this at once.In ECMA (and anywhere else) specified channel bit rate is not the same as (usefull) data bit rate velocity!Quote:Originally Posted by pinto2I know it might be confusing when ECMA standars in same line mentions "scanning velocity at -channel bit rate of 26,15625 Mbps- which of course can give the impression of reference velocity equal to 2x DVD (read/write) speed.
Read here how the channel bit rate for DVD's is calculated.
If we return back to data bit rate velocity, we'll get our calculation right. 11.08Mbps is equal to ~1,320MB/s (1350KB/s) and this is equal to 1x DVD (read/write) speed.
Conclusion. When ECMA refers to scanning velocity of 3,49m/s it means the same as; scanning should be done at 1x speed.

Finally! Some sense! Congratulations pinto2! You win a prize for making a sensical statement.....Quote:Originally Posted by pinto2Way off topic

Well, actually...there is no prize, but have comfort in knowing that you have waded through technical incorrectness and lack of understanding to find the truth and facts!
Meanwhile, thank you all for your enthusiasm. Nic and our testers are working *very* hard to get this right for you all. I am informed that they hope to provide a new version for public scrutiny quite soon.

I guess there was no confusion in hwp's answer. He just agreed that Plextor drives scan at 2X speed instead of the 1X speed specified in ECMA guidelines. It seems that you misunderstood sg.Quote:Originally Posted by pinto2Way off topic

New Version 4.52 is out...
Improved the Jitter a little...
Still not 100%... - Posted:

I wonder if it will ever support the Plextor 760A? It would be nice (scans with Plextools are an all day event). __________________

Well, 4.6.1.4 is now out. Supports a lot more BluRay and HD-DVD devices for RPM, CRC, PI/PO etc.
As for the 760, yes, I think we can manage that.

Thanks zebra, it would be a great gift for me. And I promise to make a donation.Quote:Originally Posted by zebraWell, 4.6.1.4 is now out. Supports a lot more BluRay and HD-DVD devices for RPM, CRC, PI/PO etc.

Thankyou very much zebra for taking the time to respond to my request. I will log in an offical work requests log to have the Plextor 760A included in a future version of DVDInfo Pro. Thankyou and thank NickW for your good work, it is appreciated on this end also.Quote:Originally Posted by zebraalan1476 - thank you for your input and support. It is most appreciated. If you would like to contact, and ask for this support officially, just log a job at the DVDInfoMantis web page: HERE
We will then put it into the offical work requests log, and it will get processed for inclusion into a future version for you.__________________
