It was actually effecting both buffers (to the point they had to recover - I think), I will need to keep an eye on it though cause it seems to tie in with the downgrade of quality on the 2nd layer. Is there anyway to change the settings of the OPTIARC? something simular to the (EEPROM the iHAS uses), it feels so limited when burning a disc with the OPTIARC, like if something goes wrong there is not much you can do except switch the OPC on or off. I contacted Primera last night to see if I could have access to the 1.Z8 firmware but I was politely told that it would only be accesable if I had a Primera Bravo model which makes sense I guess. I will flash Liggy's unlocked 1.Z7 revision for now, then maybe mess around with the drives speed settings in MCSE to test cheaper media at lower speeds like I did with my iHAS. I am now trying to contact the vinpowerdigital in the hope that they might link me to the 1.Z8 firmware since I bought it from them.

Cheers for the info LUK I will keep an eye open for the public version... I had the Aones singing a lovely tune at x2.4 speed (MCSE) on my burner max iHAS but once I went up to x4 they got all glitchy, I guess you can only push them so far, I'm gonna burn 3 in a row with the OPC on now to see how that fairs, that 2nd layer can't get any worse... The MKM001 and MKM003 discs are superior in every way but that would not be any fun now would it p.s. one other small thing I noticed, my Optiarc seems to stop burning around the layer break with the buffers nearly completly depleted, no big thing I guess but the iHAS never did this...

I have been running some tests on my 5250 CB PLUS and noticing that the 2nd layer of the ricoh media I am using is coming out pretty terrible, It still early days having only burnt 3 discs with the same settings but wanted to get my hands on the new firmware and maybe a list of revisions/improvements... unfortunately the only place I can find it is primera and they require a password... Does anyone have any feedback on the new firmware? It appears to run in Overspeed according to the scans, and where I might find the file?

The latest firmware I could find was from Liggy's blog 1.Z7 and that included the original firmware also... (Not sure what firware will be on the drive when it arrives - I will let you know) Is there a more recent firmware out there? I checked the NEC site but read something on MYCE about them no longer supporting thier optical resourses (or something to that effect) and that this is now dealt with by Sony Optiarc directly. It's good to hear that those guys are open to your input, and full bitsetting is a must nowadays, let me know if you get any feedback...

When I get the drive I will do plenty of burns with the cheap Aone Gold Plus DL discs at different speeds (as you did in your very own tests), I won't be testing any other media for now, but it will be interesting to see how the PLUS and ROBOT models compare, there should not be any great difference but I will let you know and give you the IMGBURN log and dvdinfopro PIF/PIE/JITTER scan if you want them. My iHas 624B writes the Aone Gold Plus DL discs at 2.4x (not native but modified with MCSE) with a quality value between 80% - 92% (DVDINFOPRO) now after much time, patience and what I consider to be a fully set write strategy, I can say it is consistant now with the cheaper media. I really want to see how the PLUS drive sizes up, specifically at 4x and 6x speeds, 8x is probably a no show, I will also use Liggy's firmware with the Booktype patch so it can be set the burn as DVD ROM.

That does make sense, (especially with Kprobe 2!!!), I am guessing there would be no problem doing a scan with DVDINFOPRO and the ROBOT in tandum though...

Yeah that would really be fun, I think if push came to shove I might have done it that way though. Fortunatly it will be sent direct so I only have to worry when it hits Cyprus Shores, My iHas624-B has served me well but this would be a serious upgrade with proper support. + it's an Sony Opriarc the drive!!! that is very close to the one you originally recommended to me many, many moons ago. I do wonder where their idea to do this came from though... I noticed your Robot PI/PIF scan results show the drive as an iHAS which was a bit weird.

FIrst I got an undelivered message but later that day someone got in touch with me and told me they don't have a distributer in Cyprus. After speaking with them further they mentioned that they could send me one directly, after some more discussion VAT etc. they sent me a pro-forma invoice and now I am just finalising the courier fee's etc. Not that cheap but I like the idea of having one of these badboys. I can PM you any further info if you need it LUK. Cheers again.

Scrap that... Someone just replied I am ordering a PLUS version, this thread can be deleted or closed now... Cheers

I tried contacting them but the e-mail is returned to me as undelivered and their phone just rings and rings... I tried sending an e-mail to Sony Opriarc Europe also in the hope they could point me in the right direction but I don't hold out much hope... Do you have any other ideas? The U.S. seem to have buckets of them but they are invisible anywhere else...

I have been looking around for one of these for some time but only Amazon (US) seem to have them. Does anyone have any ideas whre I might pick one up with delivery to the (EU)

I have tried to burn the same ISO twice now using a dreated dvd file with the same result. I am using the c4 burner max firmware patch, and this is the first time I have had an issue like this. could this be a problem with the file or HD?

Here is the 2nd image I have burnt using your settings. As you can see there is definatley a simularity with the first burn, and certainly an acceptable quality. I will post all new scans in this thread when I get some new discs,

My pocket always feels better after speaking with you, Your Money Lightning!!!! I only had Two discs left but I knew, after your advise they would come good. A Couple of post, burn questions for you. Do I need to clear the OPC before every burn? Can I use the same settings for regular burns and expect similar quality? Cheers, Oh almost forgot heres the Scan!!!

Many thanks Lightning, again the fountain of knowledge has proved the answers. I will try some burns tonight with your settings and post the results here for your input.

So Unknown Disc = HT and OHT (ON) Automatically OHT can only be disabled by the counter action of enabling FHT in the EEPROM settings, is that right?

That was a very interesting read Lightning, It looks like you got some stability in the end with a lot of effort!!! Can you tell me more about renaming the the MKM-0a3-00 in the table? Can it be changed back to MKM-003-00 using MCSE easily and if so would it even be compatible with the patched overburn firmware, Is the MKM003 write strategy even compatible with the patched firmware given the increased capacity?. You mentioned that as MKM-0a3-00 is classified as an unknown media so HT and OHT settings is automatically enabled, is this overridden by instructions given in EEPROM? (Basically can they be disabled manually)

Ok these are the settings I am using for these burns, the drive is a iHas624 with "patched" firmware enabling overburn courtesy of c4e. Imgburn: OPC ON Calculate Optimal Layer Break Burnt at x4 EEPROM Smart Burn ON Force Hyper Tuning ON Online Hyper Tuning ON OPC ON OS Win 7 x64 Discs> Singapore Printable Verbs (The Best) MKM003 Both discs are quite out of touch, I have read that clearing the OPC in EEPROM before every burn can assist in avoiding the huge spike at the layerbreak, it's interesting that the results are so different for the two programs (Although both are bad). I read that the drive records 8 writes for each media in smart write mode then chosses the best out of the 8, Should I keep burning with the same settings and hope that the drive realises it's self how to write properly or should I mess with the settings till I get the results needed. I remember reading that MCSE (What is this program?) could be used to rename the MKM-0a3-00 back to MKM-003-00, resetting the burn strategy, Is this something I should do? Will it still work with the overburn? If so how do I do it? Any asistance is much appreciated.

I will start a new thread.

Yeah, when I read it I was like that's not how it went down at all, anyway I thought at least we can correct that nonsense here. Anyway as far as I am concerned you both have the "G" in Genius, You have the Best burner on the planet and are a true apps junkie and a c4e is the dude that got M$ banning their own original discs while his burnt discs pass all their checks (If verified correctly).

Someone posted the below in the c4e chatroom and now it's posted all over the net on xbox forums and like, it's also has president on the c4e website. I'm guessing they got the info from this thread. What's wrong with people.

Great info Lightning, (I might re-surrect this thread when I get my burner an flash it) It pays to use the Search

Just wondering if it's true that it's possible to get a higher quality write to disc if background activity is kept to a minimum, or if thats an outdated theory due to the increased buffer sizes.

Sorry I must have mis-interpreted your post here: http://club.myce.com/f86/possible-mod-pc-dvd-writer-fw-324143/#post2609241 I thought you knew how to do it, ok so just to be straight. You can't create a firmware patch to increase the capacity of a DL disc (Overburn), you just thought it would be interesting to see it done. Looks like I am stuck with ordering the iHASX24 liteon, people are having many problems getting quality burns out of it though.

I was going to PM you but didn't want to be an @rse to be honest, so I thought I would just let you read and reply to this thread in your own time. Is an (Pathced) Firmware in the pipeline for AD-72 models enabling DL Overburns? If it is, I'm gonna cancel my order for a iHAS624 at Amazon and donate to ImgBurn (Only fair), I would love to be a tester if that is possble. Thanks.
