Changing DVD±R write strategies (results thread)

[Spartane]

Burner Drive: LITE-ON 451@851
Firmware: GSOK
Strategy: CMC MAG/F01/00 @ CMC MAG/R01/00
Disc Scanned: HP
Burn Speed: 8X
Program: Nero 5.5.10.56

Burned with the new "Force Fallback" option.

I never figured I'd be able to burn as clean at 8X as I can at 4X (and thus I'd largely avoided 8X burns), but the "Force Fallback" option, in conjunction with the "CMC MAG/R01/00 strategy change" seems to have done the trick. I burned a couple of HP discs at 8X and scanned them at both 8X and 4X just to make sure. All scans look similar.

I first tried the "Earlier Shift"/"Force Shifting" options, and while the discs were still OK, the error count went up noticibly, so I turned these options back off.

To say I'm impressed is an understatement. Definitely time to buy some more of those cheap HP discs from Tiger!

OptoDisc R04 burnt using Prodisc R02 strat and fall-back enabled. I kinda hoped that would help, but it's obvious it stepped in too late..

hi,
I write from the italia,
I have effected different tests with the princos 4x with the liteon 812 uson.
then I have tried to modify the firmware uson, replacing the strategy of writing princo 4x --> princo 8x01.
I have burning to 6x with best results of the disks burning to 4x.
the dvds burning to 6x, are legible from my dvd liteon 165h, and from the reader dvd home xplayer dvx 7000.
[/IMG]

that is it the correct road to get the best results?

1. burn with 812 uson 4x@8x burn 4x, read 165h vch12;
2. burn with 812 uson 4x@8x burn 6x, read 165h vch12;
3. burn with 812 uson stock burn 2x, read 165h vch12;
4. burn with 812 uson stock burn 4x, read 165h vch12;

regards

hmm im not getting good burns at all using the CMC R01 strategy for my F01.00 in fact its just plain bad with my 812@832 VS05 fw. heres the first 25%...so i wouldnt say this works for all fw and drives. also noticed when i burn with it i rarely seen it peak at 8x stays around 6.5x most of the time. with the E01 fw i dont see this. now mines external which may throw a big wrench into this way of patching as when i use the strategy i see my internal buffer going down (ie looks like its trying to go to 8x but cant).

[Jamos]

liteon 812@832 F01 using E01 8x
very low pis pos a bit high spikes but generally at a 4x scan thats a good burn.

[code65536]

Drive/firmware: SOHW-832S, VS05 (early-shifting, forced-shifting)
Media type: PRODISCR02-00, inkjet printables from ACCA/Rima
Burn speed: 8x

After seeing kwkard have good results with using the YUDEN000T02 strategy for the PRODISCR03, I got the idea to try out that same TY strategy one of my R02s. The results are about identical to what I got earlier with the PRODISCR03 strategy.

So here's my PRODISCR02 burned at 8x using the YUDEN000T02 strategy



Refer to my post earlier in the thread for results with the stock strategy and for results with the PRODISCR03 strategy.

Hi Guys

Im really happy with the new omnipatcher Before omnipatching it without changing the write stat of this disc, the disc PI/PO were 200-300/~50-60. And now LOOK @ this wonderful burn for a no name media which doesnt have any media/manufac id(burned with Nero 6.3.1.17@4x, change write strat: Media ID 01@ProdiscR03). It seems that Liteon loves Proddiscs hehe.Thx a lot code ^^.

812@832 VS05 prodisc R03 using Taiyo Yuden T0101 strategy just to see if all the yudens work well with the r03s..8x burn

[Jamos]

Burner Drive: LITE-ON 412@432
Firmware: VS05
Strategy: CMC MAG/F01/00 @ YUDEN000T02
Disc Scanned: HP
Burn Speed: 8X
Program: Decryptor/ELBY engine

since the Taiyo Yuden strategies worked so well for my R03s i applied it to my hp CMC f01.00 disks since i can not get good results with the overspeeded CMC R01 8x and this drive (still skeptical of the post from spartane that the burn above was actually done at 8x..ie nero really burned it at 4x even though he choose 8x ) but who knows maybe his 851 is a better burner (not likely though), any ways i would consider this strategy very good for CMC F01.00 disks burned at 8x using YUDEN000T02
strategy

[rdgrimes]

Drive: 1213S TS08
Media: Fujifilm03 8x DVD-R

I'm not sure if this qualifies as an actual swap, since LiteOn thoughfully left Fuji03 out of their firmware altogether. (along with a few others) So I renamed an unused strat as FujiFilm03, then swapped it to TYG02 and burned at 8x. This was a close call between TYG02, MCC02 and MXLRG02, but after repeated scans in different drives, TYG02 won.

Burned at 8x with TYG02:

[code65536]

Drive/firmware: SOHW-832S, VSC3 (early-shifting, forced-shifting)
Media type: PRODISCR02-00, inkjet printables from ACCA/Rima
Burn speed: 8x

After seeing Jamos have good results with using the YUDEN000T01-01 strategy for the PRODISCR03, I got the idea to try out that same TY strategy one of my R02s. Unfortunately, I forgot to save the scan. So I'll just describe it to you: the results were identical to the @PRODISCR03 results, except for one critical difference: there were a lot of servo errors near the 6x and 8x shift points. I later took a look at the disc, and it looked like that there were two unburned rings at the shift points.

I switched back to PRODISCR02@PRODISCR03, did another 8x burn, and everything was okay again.

So the T01-01 strat for the R02 Prodisc was not successful (but T02 and R03 works nicely for the R02).

Here's a Ritek G04 (Datawrite Yellow) using the G06 strategy at 8x. I have to admit I'm pretty impressed

[Jamos]

Burner Drive: LITE-ON 412@432
Firmware: VS05
Strategy: Prodisc R03 @ YUDEN000T02
Disc Scanned: HP
Burn Speed: 8X
Program: Decryptor/ELBY engine

before you freak out about the end let me tell you its a physical defect at the end of the disk. apparently this batch of R03s i got at www.accaproducts.com is a lemon. these defects started to happen about the middle of my 50 spindle. so like i said in another post beware r03s. but other than that the write strategy looks excellent.

[Spartane]

Burner Drive: LITE-ON 451@851
Firmware: GSOK
Strategy: CMC MAG/F01/00 @ YUDEN000/T02/00
Burn Speed: 8X/4X
Program: Nero 5.5.10.56
Full Disk

I tried this strategy because it was recommended by Jamos as an alternative to the CMC MAG/R01/00 strategy that I posted about earlier.

Here are a number of burns made with the YUDEN strategy. Option "force-fallback" was enabled ONLY for the first HP burn where it was the only option enabled.

1st disc: HP with "force-fallback" burned at 8X.
2nd disc: HP with "earlier shift" and "force-shifting", burned at 8X.
3rd disc: Khypermedia with "earlier shift" and "force-shifting", burned at 8X.
4th disc: Khypermedia with "earlier shift" and "force-shifting", burned at 6X.
5th disc: Khypermedia with "earlier shift" and "force-shifting", burned at 4X.

For the 1st HP disc burned at 8X, I found that the error rates jumped near the beginning of the burn, and I found that with the "force-fallback" option turned on my error count would ramp at the end of the burn - but only when scanned by KProbe at 8X (image NOT uploaded). So I turned this option back off.

The next HP (2nd disc at 8X) burned fast at 8 min, 39secs, and provided a great scan at both 4X and 8X KProbe speed selections. This burn was both fast and essentially perfect.

The 3rd burn used Khypermedia discs and was again burned at 8X. It should be noted here that although the two disc brands (HP and Khypermedia) share the exact same media code, the HP is a much clearer-burning disc. The KProbe scan looked good when scanned at 4X but unfortunately it looked significantly worse when scanned at 8X (image NOT uploaded), in that the error rate doubled during the last 15% or so of the disc.

The 4th burn (again Khypermedia) was done at 6X to see if I could eliminate this error jump, but the problem was a bit worse - it's even slightly visible in KProbe's 4X scan and it was a LOT worse (PI FAILURES peaked as high as 20) in the 8X Kprobe scan (image NOT uploaded).

The 5th and final Khypermedia burn was done at 4X. Note the big error hump from about 1/3 to 1/2 of the burn. It would appear that the 4X YUDEN strategy is NOT optimal - at least for my drive. This can also be seen in the first image where the error rates jump near the beginning of the burn.

Owwwch not nice... tried a ritek g04 purple ritek brand at x6 with mxl-rg02 and didnt like the results

disc is unreadable in x6 region. x4 looks sweet though

Heres the scan

[Hans Gruber]

Here's a G04 using the MXL G03 strategy, not quite as good as using G06.

[IceBerg]

Got a bad batch of media burnt nothing but coasters so I thought I would try a strategy swap to see if that helped may be a fluke but time will tell.

1st scan is “Record” GSC002 @ GSC002, 2nd scan is “Record GSC002 @ GSC001 no other mods to firmware, both disc are from the same batch code.

The 2nd scan is very similar to that of a genuine GSC001 on my burner, not as good but a lot better than the standard GSC002 and it plays in my stand alone. I'm glad I held on to that bad batch

- as expected, stock CMCMAG F01 strat, peaks at end of disk
- improved CMCMAG F01 with F01/E01 strat swap and ForceFallback
- no negative effect on Ricoh R01/R02 strat swap
- just as good as US0J, DRU700 VY02, VS01-CodeBurnFix-ROM-R1,

This is a test done with ProDisc R03 using TY02 strategy swapped with OmniPatcher.
I think this would've been quite good had it not been for a spike somewhere.

I think it is safe for you to ignore that single-line spike; it's a reading glitch and not an actual burn defect. --Code65536

1213s w/ TS08 FW
TY +R T01/00 Media

I had trouble producing a successful burn even @ 4x w/ the default strat with this quality media. I can confirm that the Ricoh R02/R03 strat is better than the default Liteon strat for TY T01/00 media.

First pic - Burned @ 4x w/ stock FW

Second pic - Burned @ 4x w/ Ricoh R02/R03 strat

A follow-up to my previous post, here's a burn of T01/00 @ 8x using the Ricoh R02/R03 strat. I'm not getting quite the results that rdgrimes is getting...

[Vertigo]

1213s w/ TS08 FW
TY +R T01/00 Media

Another follow-up.. Here's a burn of T01/00 @ 4x using the TY T02 strat. PI errors are marginally higher than with the Ricoh R02/R03 strat, but PIF errors seem to have fallen.
