BenQ drives scan in ECC blocks of 8, Liteon scans in ECC blocks of 1. So in effect, a 95 on a Litey will be a 99 on a BenQ.

Tokijin is correct about the 8 ECC blocks for BenQ and 1 ECC block with a Lite-On. Although the BenQ will show higher PIF, the quality score should be similar. Not exactly the same but similar. I prefer to scan with my BenQ because 8X is a good scanning speed for it and lite-On should be scanned at 4X. Nero CD/DVD Speed test now supports scanning with Pioneer drives, but the results are horrible. My Pioneer 109 is the best reader that I have, but it is totally useless for quality scans.

so I can't seem to find it anywhere else on the forum, but how does using bad media damage a unit's laser, I understand how using bad media would give you poor images (if you are burning videos) and data degradation but how does that damage the unit?

A bad medium cannot damage a laser diode unless the disc is so warped it whacks the optical pick-up. (This amount of distortion would be very noticeable because the disc would not sit flat in the drive tray.) During recording when the power is at its highest level, a drive will pass over an imperfect spot. A CRC error on playback means the drive will attempt to read a series of blocks at low power (0.5 to 1.0 milliwatts) a specified number of tries until the drive gives up and reports a CRC error. There were cases in which early Pioneer DVD-R drives could choke on 4X DVD-R discs and keep attempting to write to them at high power until either the diode burned out or the drive motor gave up, but this was because the early drives did not recognize 4X discs. It was not a question of quality; firmware updates took care of the problem for those early drives.

In the case of the PS2, crappy dyes will wear down your laser much quicker than Taiyo Yuden or Verbatim media. The crappy dyes force the laser to strain more to read discs, hence shortening its life. You can get Taiyo Yuden for cheaper than CMC Mag or other crap media. I've burned close to 300 PS2 games on Taiyo Yudens and Verbatims with 0 coasters (95% to TY's) in both formats. In the case of standalone players, JoeRyan may be right. Regarding the PS2, always use quality media.

THANK YOU! Thats the answer I was looking for, another thing is that I am not sure if my PS2 likes -Rs or +Rs, how do I test for it, it seems to like both of it.

V.4 PS2's and later will play DVD+R's book typed to DVD-ROM and DVD-R's equally well. I've burned half of all my backups to 8x Taiyo Yuden DVD-R's, and 8x Taiyo Yuden DVD+R's. They play equally well. I have a v.4 PS2 modded with a Matrix Infinity. I prefer DVD+R's, because they tend to be of better quality. That has to do with how they're manufactured. Others who're more qualified can inform you of the specifics, it's pretty technical.
86. Q. Where can I find good deals on legit Taiyo Yuden's and Verbatim's?
A. http://www.supermediastore.com
Great List of Merchants locally, online, in the U.K., etc:
http://www.digitalfaq.com/dvdguides/buyerguides/buymedia.htm
106. Q. Where can I find top notch Taiyo Yuden or Verbatim media locally?
A. This is somewhat of a crap shoot. Big manufacturer's like Fuji and Sony have at one point past or present payed Taiyo Yuden to manufacture media for them. The big companies slap their name on the label even though the discs were manufactured in Japan by Taiyo Yuden. These discs will always be made in Japan. Authentic TY media isn't made anywhere else. Even if it says Made in Japan on the label, there is no guarantee of getting authentic Taiyo Yuden media. You could still end up with Sony or Fuji media codes. Hence why I said this is a crap shoot. Places like Comp USA, Office Depot, Sam's Club, and Staples will carry Made In Japan branded discs. Again there is no way to know for sure from the package whether these are authentic Taiyo Yuden's. The exception is that Sony MIJ 8x DVD+R's will always code out as Yuden000T02. If you don't want to risk getting non TY discs, you can find 50 packs of Verbatim in the afore mentioned chain stores. One other alternative is the Made in Japan High Grade Maxell DVD+R's. They will say Made in Japan on the label and "High Grade" as well. These are excellent media. Remember when using DVD+R's, it's best you have a burner that supports booktyping/bitsetting, and a v.4 PS2 or later. Much thanks goes to kivory666 aka "docTY" for this information. He is indeed the Taiyo Yuden master. The best place to get authentic Taiyo Yuden media is from reputable online vendors like http://www.supermediastore.com http://www.rima.com http://www.meritline.com or http://www.newegg.com
23. Q. What version is my PS2?

Well to the untrained eye that's good, to vets of CD-DVD Speed, it needs some definite improvement. Your Max PIF's and average PIF's are pretty high, especially for Taiyo Yuden. Are you closing everything down while you're burning, including scanners, AV, Internet, etc? Is your firmware up to date?

i probably had some applications open when i burned it. i was going to flash my drive but it said i already had the latest firmware but for some reason my drive wont read dvd's or cd's but it can burn them and tell me if it is blank or empty, i just can't get it to play any media or recognize any media.i'll do another burn with applications closed and post it.

Hmm the average PIE's are still too high. They're better. I'd say make sure your burner is in DMA mode. Anyway, CD/DVD Speed scans are just a barometer, not absolute. How do your backups play?

i have no problems with my backups at all which is why im curious about my scans if i do have glitches its because i backed up from one of my older originals that might have a few scratches on. my drives are both in dma mode. here is a scan i made from a burn with my LG (HL-DT-ST DVDRAM GSA-4167B DL12) drive. (for some reason it wont let me start the disc quality scan with this drive so i had to scan it using my nec drive .(this was also backed up from a older original disc)

Yeah I don't think CD/DVD Speed supports LG drives. If your backups play fine, then don't worry. My standards are a little higher than that of the average person. A quality score of 90 is considered excellent. If you don't have any playback issues, then you don't have anything to worry about.

I am very new to this, pls be patient. My country does not sell TY. The verbatim I try sometimes cant plsy on verious player (Taiwan), I have used Imation (Taiwan)n so far no trouble but I am very troubled by this CMC Mag that I read in your forum. Does that mean my disk won't last? I use sonic (Nero) so I can't do a scan but DVD identifer (I just learnt today from your forum to dl free)the dik i use is :Imation DVD+R CMC Mag AEI
Imation DVD+R Moses Baer R04/001
Maxell DVD+R Ritek R03/002
Emtec DVD+R Interaxia AG 001/001
But becos pic quality is important to me, I find Imation is sharper than Maxell and sound is sharper too
I don't use Sony becos pic quality not like the above, only colour nice.
Pls advice Thks

I repeat: a bad disc has no effect on a laser diode. It does not strain--it has a fixed output. It may stay on a bit longer as a drive tries to read a sector more than once, but dye quality has no effect on the aging of a laser.

Bad Media will speed up the demise of the PS2 laser. In general, I agree with you, just not in the case of the PS2.

Hi everyone...couple of questions...
I am wondering at what speed I should set my Nero cd-dvd quality speed tester. For example, if I burn a dvd at 6x, should I put the Nero cd-dvd quality tester at 6x too or what? What if I set it to 8x, would that give me more errors.
Also, if you get low quality rating, does that mean your disc will skip, data within it will dissapear after a short period of time, or what?
Recently I bought me a Verbatim, which has the MCC004 Media, which is suppose to be top quality, but when I burn at past 6x i get a quality rating of 0-30. Please help.

Same disc, same computer, 2 different drives. What does this mean?

It means both drives read the same disc differently....as to which one is more accurate is anybody's guess. That's why I gave up trying to figure out scanning quality scores and just use good media and 4X to 6X burning speeds and if they play fine then that's great. You can run yourself crazy trying to figure out quality scores like this.
