New Toy: DVDScan and Feedback Here:

Actually no one here has yet confirmed that it works, so maybe it's not related to our drives being external. It does list my drive in the program, it just says 'no disc'.

Well, I had the same problem with my liteon 16h5s drive. I had to disconnect all my other drives to get it to work (not phisically - just disabled in device manager).

The pi test works fine, but the results are rather strange (the pie are fine in pisum8 mode, but much lower in pi mode - it's probably just different counting algo. The pifs are very high - even 4-6, but in cd/dvd speed they're at most 2!).

The beta and TE/FE tests also are working fine but are terrible slow. I can't get jitter test to go past the first lba (see attachement for the shot - 0.1% and 0x000000 for 20minutes).

And one more thing. Once the work on main algos and features are done, this Tom guy should consider changing the gui, it's awful and unhandy (IMO).

Resized the picture because it was messing the thread display when at original size

Hey, guys
This was not Tom's job. I asked him if he could do that favor for me and he kindly did. So, please be nice to him. I believe there must be a lot of problems for this beta version. Just try to find the most useful way of your own. (This version is good enough for me and I usually use it to measure jitter and look at the pit/land histogram only, at 4x speed. ) I think Tom will check all the problems/requests and try to fix/implement them. Give him some time to work out.

I agree 100% with this!
You and Tom as well as Karr are helping us out here on the LiteOn forum in a way, that is both admirable and very valuable.

I don't think it's helpful to "reward" this by us complaining or being ungrateful.

I for one think that the LiteOn drives and the LiteOn forum have improved immensely due to the voluntary and excellent work done by our friends at LiteOn!

I'm really looking forward to using the capabilities of this new DVD Scan program, and I just hope that it will be possible to use it with my external 1635S drive.

But even if that should never happen, I'm certainly not going to complain about it!
...but I might have to shed a small tear quietly by myself.

Does the current version only work with an internal drive, and only if that drive is the only optical drive in the system?

Looking forward to it!

Thanks guys ...the reasons for retiring my 1693S for one of my 1635S's keep mounting...

Was it me, who was not nice? If that is the true, then I'm terribly sorry . It's probably because of my bad english if the post coud've been considered rude/ungratefull/not nice... I still have serious problems expressing my thougths in english...

Anyway, the jitter test hangs for me after first block... Everything else works fine.

I've made some tests with this versoin of DVDScan. The drive was a lite-on 165P6S firm MS0M and the media an TDK branded TTH02 burned with PIO111@8x and here are the conclusions (please take 'em like constructive criticism, i have no intention to upset the author ) :

- I have to disable the PIO111 from task manager to use the program.
- The PIE/FIF test is fairly accurate, inline with what Kprobe reports.

Overall it's a very nice try for a first version, needs a little pollishing but i hope that everything is gonna get better in future versions. Good work Tom

Now here are some scans :

Btw, can any1 please tell me where i can get some information on TE/FE and Beta scans? I have no ideea how to interpret them.

Later Edit:
I didn't realised that i need a special firmware for DVDScan to work, so i removed some points made. I'll get back with further details after i flash my drive

I'm not sure, but I thought that test firmware would be necessary for this program to work?

A brief explanation of Beta can be found here.
Beta should be close to 0% (-5% to +15%) and should not jump suddenly up or down.
Until now, Plextor drives have been the only consumer drives able to scan for Beta.

Tracking Error (TE) is how difficult it is for the pickup to follow the track.

Focus Error (FE) is how difficult it is for the pickup to focus the laser at the correct depth.

I don't know which units are used for measuring FE/TE, but there seems to be builtin indications of acceptable limits in the DVD Scan program.

Plextor drives can perform FE/TE scans with PlexTools, and BenQ drives can perform FE/TE scans using QSuite, so you could go and perform searches in the Plextor and BenQ forums.

. I'll go hide some where

And thx for the info regarding the TE/FE and beta

After flashing to MV94 the jittler scan is working. All the other scans posted above with MS0M are identical with the ones obtained with MV94. Great tool

I totally agree, for me there is nothing to add, apart from a big bold thank you guys

@Wind, this tool looks really great and I really want to test it but it always just displays the information for the virtual drive and I don't see a possibility to select my 165P6S which is connected to secondary master

/edit: virtual drives disabled, and now it selects the NEC one.

Anyway, I'm looking forward

link gives an error so i can't dl.



ps wind why haven't you replied to my pm's?

Here's an alternate link I posted - http://www.savefile.com/files/1689876

Disable the NEC writer from the device manager. It worked for me with a PIO111 as master and 165P6S as slave.

Wind and Tom: Thank you very much for making this tool available- it definitely adds to the "playing" value of the 5S and 6S drives!

Thanks too to scoobiedoobie for posting the alternate source- Wind's links didn't work for me.

I too had to disable all my other optical drives in the device manager before it worked, but I'm sure that'll change in later versions.

Attached is my first jitter scan (an ancient test disc from my first burner: RicohJpn R02 burned @12x zone CLV in LiteOn SOHW-1213S fw TS08 ) and the corresponding KProbe scan.

I'm going to have a lot of fun with this toy. If you're open for suggestions, I'll draw up or add to a wish list.

YAY! And i thought that my TTH02 jitter was bad....

Wow, Tom and Wind! You folks rock my world

After using it for 20 mins., here is my feedback:

The good

• awesome new features that are very handy and guaranteed to keep me up later at night
• the real-time charts rock! Karr, please add this to KProbe
• the max PI/PIF values are very handy! Karr, another KProbe request

Feature requests

• copy disc LBA End value to test LBAE
• ability to scan CDs
• resizeable window and graphs
• ability to save screenshot
• 10,12,14,16x scan speeds for PI/PO, jitter, and beta tests [may not be accurate, but it's nice to have as an option]
• PIF total field under the PI total field
• disc MID display field

Improvement suggestions

• does not work when non-Lite-On drives are present -- ejects all trays
• in jitter test, % progress does not work
• reads disc booktype rather than disc type (DVD-ROM instead of DVD+R)

I'll upload one screenie.

Once again, thanks a lot for this! Looking forward to the next version

Good suggestions alexanderino. One more, from myself and DrageMester: Functionality with USB/Firewire external drives. I just disabled my other drives and it still lists 'no disc' for my 160P6S in an external USB enclosure. I'd love to be able to make use of the program, hopefully I can keep my drive in its enclosure. Thanks again Wind and Tom.

Here's a 4x jitter scan of a Fujifilm 8x DVD+R [YUDEN000 T02] burned with a BenQ DW1650 sorry, the Lite-On SHM-165P6S -- I expected better from this combo

Hmmm, the 2x beta scan test didn't take as long as I thought it would At 8 minutes, there is no real need for 8x or higher, as the results could well be useless.

Do you have a scan of that disc scanned in your 1650? I'm very interested in seeing how the jitter levels reported compare between drives. It's already seems to me that A) The Liteons report overall jitter levels higher than Benqs - I don't necessarily see that as being a big deal, if they both test to similar scales of increase the results should still be able to be 'translated' from one drive to another. B) Looking at MediumRare's scan above, the abrupt increases in Jitter that Benqs would report with some Liteon burns that were questioned for validity by some people, those abrupt increases also show in his scan so either both Benq and Liteon drives are now not to be trusted, or perhaps those sharp jumps in jitter that Benq drives have been reporting are accurate after all. I have personally always believed the abrupt increases were legit, but that's still debatable and probably always will be to some extent. I can't wait to use the program, I may have to break down and take my drive out of its enclosure. (as I look down at the literally dozens of twisted cables behind my tower )

My apologies! Looking through my scans, I now realise it was done with my 165P6S and not the 1650. Here is the KProbe scan:

http://club.cdfreaks.com/showpost.ph...&postcount=178

The BenQ scan is attached. Yes, the jitter is constant and lower.

Since I can't edit my post, I'll just quote it.

I disabled a virtual drive that was on my system, and now I've got it working.

Thanks alot. Looks like the overall trend and scale of increase (or lack of it in this case) in the jitter is very similar between your Liteon and Benq, with this disc. Roughly a 3.5% increase in the overall average, otherwise quite agreeable in the reported jitter levels. Hopefully future scans are in relative agreement, plenty of comparisons are due now.

Wow! Thanks Wind and Tom. This looks brilliant.

I apologize for the couple of posts from people that don't seem to appreciate what you have done here. They obvious have no understanding of what is involved in putting something like this together and how grateful the rest of us are.

El_Mariachi_X, is already on probation and will find himself banned soon if he keeps this sort of thing up, including pestering people with PMs.
