Are TEON DVD+R's total crap?

[marioman]

My 1st spindle of DVD's are DVD+R 8x by TEON

Well the few DVD's burned out of it @ 8x were fine, now if i burn at 8x its a guarunteed coaster. out of a 40 pack over half are now coasters.

I've started burning them at 6x with no problems, but today i burn 2 DVDs both at 6x, 1st DVD fine, 2nd DVD is a coaster...is this a total crap product or is it LITEON burners?

I've been using both Nero 6.6 and DVD Decrypter to burn DVDs.

Get DVD Identifier (http://dvd.identifier.cdfreaks.com/) and let it retrieve the media code of your discs, as that is what really matters to determine the quality.

ok DVD Identifier Info on these TEON 8x DVD+Rs:

(side note: isnt that interesting how do they get 4.38GB from 4.7GB? lol also noticed that the label on them says 4.7GB but they are really 4.38GB can we say false advertising? lol)

btw this brings about a side question that has me puzzled: What are the time ratings for? These DVDs say 4.7GB DATA/120min Video but I can fit 3hrs+ on them...It's obvious the time doesnt matter as in DVD Decrypter it says max time is 510mins...just not too clear on the whole Time info thing :\

A mega(binary)byte is not 1 million bytes; it is 1024*1024 bytes.

A giga(binary)byte is not 1 billion bytes; it is 1024*1024*1024 bytes.

4.38 GiB (gigabinary bytes) = 4.7 GB (SI gigabytes).

That is, 4.38 * 1024^3 = 4.7 * 10^9.

They just picked some average bitrate to come up with those numbers.

ah hmm

i was thinking gigabit vs gigabyte...

what is this SI gigabyte u refer to? never heard of those
always figured a byte is a byte is a byte, and a bit is a bit. didnt know there are two different kinds. whats the difference of these 2 bytes? and what is the most common type used? does windows read the binary or SI byte? i know it says 4.36GB for say a burned DVD if i look at file info etc...

always figured a byte is a byte is a byte, and a bit is a bit.A byte is a byte and a bit is a bit. There are not two different kinds. There are different ways of counting them. It's like a baker's dozen versus a normal dozen.

[marioman]

So basically the SI system is inaccurate compared to how a computer reads them.

Anyway back on the topic of my post, the TEON's are crap, maybe Mitsu should go back to focusing on cars lol

Just burned 2 4x FujiFilm DVD+Rs and not a single blemish on the underside the TEON's had a break in the surface after burning at about 1/4" from the center edge. You can see where the color goes from dark purple to a swimmy combination of dark/light purple then back to dark (i think its where the disk spins up faster the 1st time which it does twice during the burn process)

The Fuji's are Ricoh just too bad they are 4x takes forever to burn and gonna take foreverto use these 100 Fujis (well 98 now lol)

Actually it's the other way around, SI has been around a lot longer than computers. :)

Did you have burning/reading problems or is this based only on the visual appearance of the disc?

[code65536]

Teons are fairly good media, IMHO.

What LiteOn model? Firmware? Can you provide a KProbe scan? Etc.?

[marioman]

I'm talking reading problems, even have had 2 disks fail to write. Most wrote but could only play the 1st few mins of a movie then would spit out a read error. The 1st....id say...10 or so...burned fine w/o problems then as i got farther and farther down the stack they got worse and worse. Some i did at 6x most of those worked, until today i started to have probs with 6x burned DVDs.

As for the burner, its LITE-ON DVDRW SOHW-812S running firmware US0Q.
I just upgraded the firmware from US01 then burned a DVD @ 8x fine, then went to burn a 2nd and it crapped out on the last 2 TEON's I had so I'm using the fuji's now

The reason i mentioned the blemishes on the underside was because this seems to be where the read errors occured.

I just picked up Kprobe, which scans would u like?

A DVD+R disk can store approximately 4.7 billion bytes. This fact doesn't change.

That's 4.7 gigabytes using the SI definition of "giga-".

That's 4.38 "gigabytes" using the wacky computer industry definition of "giga-".

Do a BLER scan. Of the first disc that burn okay. And the 2nd disc that was "crap". Please do the scan at 4x. Save the scans (see the diskette button) as PNG and post the images.

Edit: Okay, just noticed your burst rate. Turn on your drive's DMA. You can't possibly get good burns with a 3.8 MB/s burst rate!

(you were using US01 before this?! omg...)

[marioman]

the drive is running on Ultra DMA Mode 2, at least thats what windows says, I have the use BIOS setting checked.

And yes I didnt initaly upgrade the firmware cuz i went by the dates, the drive came with US01, the date for US0Q is July i got the drive right b4 christmas so i figured it wouldnt need it (note: i never actually noticed the firmware designation until i went back to the website lol.)

[marioman]

code: after checking that FAQ u have linked in ur sig and following the guide to enable DMA, theres one part that well isnt accurate. I dont have Primary and Secondary channels listed seperately under device manager, the only thing i have list is the IDE controler, well here's a pic of what im talkin about, will be easier than explaining...lol

[marioman]

Well isnt this just (as we say in a MMO game i play) "teh sux"

Ok for the life of me i couldnt find anywhere to make the nForce 2 drivers show the channels seperate like i've seen in screen, so i went back to the MS Standard IDE controller driver and several reboots later my burst rate is 26.86MB/s now

So here's a warning to all nForce chip users out there, DO NOT USE THE NFORCE IDE CONTROLLER DRIVER AS IT DISABLES DMA....atleast apparently it does, didnt affect my HD's any...hmmm now maybe my secondary DVD-ROM will work now, I was having problems with it plugged up before.

Thanks for the help guys this has been a very informative topic :D

Now if i hadnt wasted all my fast DVD+R's BAH! lol

oh well live and learn i guess hehe
