Hi guys.
I was wondering if anyone had any direct experience with pot calibration tweaks on Lite-On drives. I've read that somewhere between 4-6 Ohms is acceptable, but I would really like some first-hand observations.
If you have ever tweaked the pot on your Lite-On DVD drive and got it to read backups that were previously unreadable, please post here with the resistance that you set the laser to. I've got a dying laser that doesn't seem to like all of my backups no matter where I set the resistance...
Your help is much appreciated. Thanks in advance.

Thank you for the advice!
Much appreciated. There is so much conflicting info about pot tweaking Lite-Ons that I appreciate some validated results.
Anyone else?

I just did this last week as it were. My disc drive wasn't reading any games at all, burned or retail copies, so I did this as a last ditch effort. The base reading I got was something like 5.3 Ohms. I read somewhere that the "butter zone" was between 3-3.4 Ohms, so that's what I went for. After about 30 minutes of frustration, I finally got it set to 3.24 Ohms. It boots games now, although for some reason cheap Windata discs seem to work better than Verbatim's. I had burned the Episodes of Liberty City and Dragon Age on Verbatim, tried them with the One Shot Boot, and they would freeze. I re-burned them on Windata's and what do you know, they work fine. Anyway, I guess try the 3-3.4 range.

Same here! Cheapo Sony (rebranded Ritek) disks will boot, but Verbs won't boot in my Lite-On!
I am glad to see that I am not the only person having that problem and that it doesn't mean that the drive that I have just sucks (any more than usual, anyway).
I have no idea why this is, but it needs to become common knowledge in the 360 scene.
Out of curiosity to Aiur and bal3wolf, what firmware revision is your Lite-On? Mine is 1.6.
Also, do your guys' games on Verbs ever show up as a 'Play DVD' error by any chance?
And thanks for the info re the pot cal. I have seen so many sources say not to go under 4 for a LO, that I was too paranoid to go under that.

I have 1.6, and now that I think about it, I don't remember having any issues with 1.5. Pretty much once I upgraded to 1.6, I started having disc read problems. I wonder if we are just part of the unlucky crowd, or if this is a trend with Lite-Ons and iX 1.6.
I don't get the "Play DVD" message, I get the "Open Tray" message. Another problem is sometimes the game will boot, but before getting to the menu I will get the "Disc is unreadable" message.
I'm probably going to get a newer console, though. I had the "Open Tray" message happen again today on One Shot Boot. I tried other games as well, no luck. I finally wiped One Shot Boot very lightly with my shirt, and it loaded right up. I'm opting for a system with a Jasper chip made before they started putting the new Lite-Ons in, although if the problem originates with iXtreme and not the DVD drive, there goes $100+ down the toilet.

I just ordered a replacement laser for the drive and we will see how that goes.
If the issue is in fact with iXtreme and not with the drive itself, I suppose it is always a possibility to use the old 'Extreme' firmware as long as you know your stuff and always intelligently scan using ABGX.
Very odd indeed. I wish there were more info out there about it.

Update:
It appears that this is not a new issue. eebeejay posted about this very problem (Lite-On not reading Verbatims) about two months ago, before 1.6 was even introduced.

Lite-On: Won't read Verbatims (exception to the rule), so I use any cheap media.
So our problems are not isolated. This seems to be a common problem among Lite-On drives.

So if I'm understanding what he said correctly, the lasers on our disc drives are so messed up from using cheap media that they will no longer read the best media out there? IDK if I am buying this. My cousin only uses Memorex for his games, and he has no problems (BenQ). My older brother uses just Windata's, no problems (probably a Lite-On, not 100% sure). My younger brother mixes Windata's and Verbatim's, and he doesn't have any drive problems (Lite-On). I spend more time playing than my brothers or my cousin, so that probably has something to do with it, but I do find it odd that these problems started literally right after I got done upgrading to 1.6.

I don't think he was necessarily saying that the Memorex discs ruin the Lite-On drive and that is what makes Verbs unreadable. At that point he was just saying that his Lite-On also wouldn't read Verbatims, but would read other discs. Seems like a mighty big coincidence that only Lite-Ons have this issue.
I just went out and bought a pack of Memorex discs as well, and I am getting the same issue as I was getting from my Verbatim discs. My older Sony discs still work fine.
I set the pot to 3.24 Ohms resistance. Still no go.
Hopefully once I get that new laser it will help things. Otherwise, I guess I am shhhh out of luck. As it stands, I already have more discs than I will use in a year. Not sure I could bring myself to buy another pack of Sony DVDs just to get the same error again.

This is his full post:

Find the extended info by searching the threads. It's there. But to sum it up, no recordable media "acts" 100% the way original media "acts". The 360 will read most any DVD+R DL, but Verbatims "act" more like originals than any other brand, causing less strain on the laser than Memorex, TDK, Aone, Maxell, etc, etc, etc.
I've got three 360s:
1: BenQ: has used Verbatim only
2: Lite-On: has used Verbatim only
3: Lite-On: Won't read Verbatims (exception to the rule), so I use any cheap media. When it burns out (and it will), I'll replace it with one of the 2 virgin BenQs I have, and you will need to do the same. So be ready, and don't complain about why you laser died, because now you know why.
He's saying the strain put on the laser by lesser quality discs is what is causing the problem. It just seems like the Lite-On drives are of lesser quality than their counterparts, and not so much the discs.

Alright... get this.
My new game discs on the 1.6 iXtreme Lite-On drive were all showing up as 'Play DVD', even though I was not attempting to play any wave 4 game.
I was at my wits end after not being able to get my games to boot, ever after purchasing a different brand of DVDs.
So tonight I burned the activate ISO to a disc and tried that.... and the games all booted.
All ISO files and discs verified 100% with ABGX and with ImgBurn. The games were wave 3 (Borderlands and Brutal Legend).
I have no idea why the activate disc worked, but it did. I assume there is some issue with iXtreme 1.6 for the Lite-On, but I can't know for sure.
In any case, it is what it is. I am honestly at a loss as to why the hell using the activate disc would make any difference when ABGX thinks the games are just peachy keen.

Okay, it turns out that I had flashed the drive with the original 1.6 Lite-On firmware and NOT the repack firmware. I checked the MD5 of the file and it was different from what it should have been. I assume this was the issue all along... ugh.
Anyone care to explain to me why the repack of the LiteOn firmware was necessary to begin with?

Did you re-flash it with the repack?

Not yet. I figured that out about 5 minutes before I went to bed last night. I will reflash today. I am 99.9% sure this is what was causing my error.
Check my other thread -- 1.6 vs 1.6 REPACK. Leerage reported in that thread that the original 1.6 that was released had problems with some wave 3 games. Sounds eerily familiar.
I am just happy I finally figured this damn thing out. I have been trying to get this drive to play Borderlands for two damn weeks! Haha...

A little update to the situation. My older brother (who uses nothing but Windatas) has the same problem. I told him about my problem so he agreed to swap my Verbatims for his Windatas. I burned him the Activation Disc, Dragon Age and the Episodes From Liberty City, and he is have the exact same problems as I was having, detail for detail. I don't remember if his drive is a Lite-On or not, I will ask him when he gets off work.
