Cannot read CD-Rs but can read DVDs

I cant understand this...
Regardless or not if a CD-R is factory burned, burned by myself (in the past)or is unburned - my computer cannot read the disc and spits it out. Any kind of DVD I put in there it reads fine. I am running 10.5.4. The funny thing is, they did work... after i initially installed the system i used some of the CDs to install apps. Any thoughts?
PS: The CD work fine on my other machines and none of them are scratched.
This is what my system has to say about the factory drive:
MATSHITA DVD-R UJ-857E:
Firmware Revision: ZA0E
Interconnect: ATAPI
Burn Support: Yes (Apple Shipping Drive)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: Insert media and refresh to show available burn speeds

I have been reading these forums for a while. I have the exact same computer drive and firmware on my MBP. I read that the issue is the drive (however this was last year and can't source the info, but I did a lot of research on the subject, just never acted on it). The MBP I have also had a bad battery as well, and Apple replaced it because they admitted that a large series of MBPs were installed with this bad battery, just like Apple put in a bad drive. If your computer is still under warranty, I would take it to Apple's Genius Bar and they can run check to see if it falls under Apples' "recall" computers and they should replace it. They did that for my battery.
However I never did the drive because I assumed they would have to hold my computer to do it and I couldn't give it up since it was my computer I used to work on my MBA.

That problem can be caused by the Yahoo! Toolbar that extents too much downwards and covers the top part of the browser window and thus makes links in that part of the screen not clickable.

Cannot import audio CD, but can play! error: required disk cannot be found

cannot import audio CD, but can play! When I try to import it appears an error: required disk cannot be found!
Does someone knows a solution?

There is no such thing as a "parser plug-in".
That's not entirely accurate. In CS4 we use "EPS Parser.8BY" to assist in parsing of illustrator files. This plugin is normally located at:
"C:\Program Files (x86)\Adobe\Adobe After Effects CS4\Support Files\Plug-ins\Format\EPS Parser.8BY"
Is this missing for some reason?

Cannot read DVD+R with GWA 4080M firmware AA26 (macbook pro 1.1)

Hi everybody,
I have a macbook pro 1.1 with a drive GWA 4080M (firmware AA26). Since a few weeks I cannot read anymore some DVD+R (Sony DVD+R media code D21).
1) One of these media burned with my other macbook pro (2.2 drive Matshita UJ-857D firmware KCVB) using the finder (so ISO9660,joliet,UDF and mode 1, booktype DVD-ROM) cannot be read on the MBP 1.1 - The same DVD is properly read on other mac or PC even on my old dell PC of 2003). I used the finder to burn it.
2) The very same media burn (data), burned using the finder as well, are read if burned by an other burner (Mac quad core, with SONY DVD RW DW-D150G). The disk seems to be similar (ISO9660,joliet,UDF, mode 1, booktype to DVD-ROM).
Actually the bitsetting (I learn what it was from wikipedia yesterday) seems to be done by default on mac (both of the burner).
3) A DVD+R (still same media) is burned properly on the MBP 1.1 with GWA 4080M drive, and readable everywhere.
4) The Matshita UJ-857D has not received the superdrive 2.1 update (if applicable, that seems to triggers problems). I experience no problem in burning or reading with this drive except this one.
I tried to reset the I repaired the permissions (there was nothing to be done anyway), I also reset PRAM and NVRAM (http://docs.info.apple.com/article.html?artnum=2238)
and SMC
(http://docs.info.apple.com/article.html?artnum=303319)
and it did not helps
Last point the problem is the same under windows (bootcamp) and mac!
I would be very grateful if someone has a suggestion to fix or at least!
Thank you in advance

my same problem..
how come we can't get an answer on this?

Can't burn CDs (but can burn DVDs!!) Satellite U400-20v

hi,
I have a satellite u400-20v. There was no problem at first to read or burn a CD or DVD but after I setup windows 7 ultimate. my cd rom now can read both CDs and DVDs and can burn DVDs but can't burn CDs (data or audio). The burner gives me an error msg as soon as it begins writing the cd. My optical drive is called Mat**bleep**a DVD-RAM UJ862AS ATA device (at the device manger).
Please help
Thanx

iTunes can be a bit flaky on 64 bit Vista since it's not supported but it has been known to work.
Try updating your CD/DVD drivers here -> http://www.gearsoftware.com/support/drivers.cfm
Also, make sure the your other firmware & drivers are up to date.

Satellite A20-130: SD R2412 cannot read DVDs burnt in certain optical drives

Hi,
I've got a Satellite A20-130 laptop, running WinXP and Ununtu Dapper in a dual partition. My 2nd laptop is not Toshiba one. When I burned DVDs (DVD+R) with my non-Toshiba laptop and played them in my Satellite it all worked fine.
However, when I bought a new optical drive for my 2nd laptop my Toshiba suddenly stopped playing the DVDs burnt in this new optical drive(I was using exactly the same disc brand and format as before-- DVD+R). I tried the old DVDs (the ones burnt in the laptop before the optical drive hardware was upgraded) and they can still by read perfectly fine.
This problem applies to both Ubuntu and WinXP. Support from 2nd laptop says this sounds like a firmware problem with my Toshiba. I updated the driver for my SD R2412 Toshiba optical drive (which, according to the file manual, seems to fix a DVD-Ram compatibility issue). Now the drive occasionally reads some of the new burned DVDs (after making loads of noise and waiting for ages), but more often than not I get an error message saying the device cannot be read because the format is incorrect or the device needs to be formatted.
This non-Toshiba laptop reads the DVDs it burns using the upgraded optical drive perfectly fine.

Hi
Satellite A20 is pretty old notebook model and after intensive usage it can be that drive is more sensitive. If all this happen occasionally there is no simply explanation why this happen.
I know it is pretty annoying but I do not see any magic solution. At the end you must test it with brand new drive.

Help needed! T40 DVD driver cannot read DVD

Dear Expert
My DVD driver cannot DVD. The DVD driver icon in "My Computer" does not show the name of the DVD and when clicked, shows "no DVD inserted".
But it can read CD.
Thanks very much for your help and advice in advance,
Cath

there is a possibility that the laser associated with the DVD reader is no longer functional, while your CD reader laser still is, as these two lasers are different.

HELP! Cannot read DVDs

Burnt two of the same DVDs with G5 and iDVD 6, made with iMovie and then iDVD 6 like many times before.
Tried to read them with G5 and home DVD player, but getting error messages, DVD cannot be read!
BUT: My iBook G3 can read the latest burnt DVD!
What is happening?
Fanny

Hi Fanny
Welcome to apple discussions. Have you recently switched brands of DVD. Tell us which types of DVD's you are using. Verbatim DVD-R Minus 4x is the media of choice and is what many will recommend on apple discussions.

My G5 cannot read DVD-R, 4.7G discs

I know it's an older model with an older Superdrive, but is there anything that I can do any programs I can download that can change it?
I use a Dual 1.8 GHz PowerPC G5, loaded to the gills with RAM and memory.
Thanks,

Awrite, here's what i've done to reanimate my defunct DVD player. First i insert a DVD and as usual, nothing happened. Just testing, tried out a Jethro CD, worked fine. Ian back in the box, now with the DVD inside the drive. Silent as a grave. So, i run the dvd player software and the Toast Titanium. Ask for disk information, no CD in the tray, was the answer. Ok, open the tray, disc info. Answer: The tray is open. Close the tray in the keyboard. Well a this point i was annoyed because never an apple DVD worked properly for me (and i am mac user since 1988) and i never found a satisfactory answer regard DVD support from mother Apple who provide us with these magnificent machines but never follow the discussions to see if we users are happy. Well, i keep asking, info and open and closing the poor tray driving my anger in this catharsis when suddenly the Dvd player software started play the movie. So, i cancel the info in Toast, quit the program and watch finally the Dvd. I think i have irritated the drive so bad that it decided to wake up, it worked this time but i don't know about the next one. True story. Better Solution? External DVD burner.

Cannot read DVD

It probably does not have to do anything with the software, but my MacBook Pro does not read the DVD. Any suggestions?

Try turning off the computer and shooting compressed air into the CD drive (use a compressed air can, or 60psi on a compressor.) Then turn the computer back on and try your DVD again. It took me 3 or 4 tries, but it eventually worked like a charm. (NOTE: If you leave your computer on while you do this, you may hit a shock switch, which will cause your drive to act "broken". If this happens, power off the hard ware and power it back on, and It should work again.)
Hope this helped!

T61p cannot read DVD-RAM

I made some back ups last year on destop using DVD RAM discs. Now back on my T61p, the discs are not read. I tried a new DVD-RAM disc and find no way to have the drive recognize them.
Is this normal or is it possible that my drive is toast?

Hello,
In this Lenovo support article, it states some types of UDF-formatted discs require that additional Drive Letter Access software be installed when running older versions of Microsoft Windows. Could you tell us more about which version of Microsoft Windows was on the ThinkPad T61p when the DVD-RAM discs were created, what tool(s) were used to back up the files, and which version of Microsoft Windows is now installed on the T61p?
Also, were the discs readable at some point by the T61p, but ceased to be accessible?
Knowing the answer to these will be helpful in determining how to further troubleshoot the issue.

Aryeh Goretsky

Cannot read DVD's on PC.

I have tried burning a few DVD's from my iMac G5 and the burn process seems to work ok. I can eject and insert the new DVD and all looks good. Now when i take this DVD to an XP machine there is nothing on it ? Is there anything i need to do when buring a data DVD to make it readable via a Windows Machine ?

when buring a data DVD
iDVD makes video DVDs, not data DVDs.

Optical drive cannot read DVD-RW after burning?

All of a sudden my built-in optical drive (Matshita UJ-857) appears to have lost the ability to mount burned DVD-RWs. I'm using Sony 1-2x media which burn & verify successfully. Following the burn, the DVD-RWs show up on the Desktop and can be browsed in Finder. However, once ejected, the drive cannot mount them again - they spin up for around 30 seconds before being ejected.
Other media (DVD, DVD-R, DVD+R, CD, CD-R & CD-RW) work fine; DVD+RW requires 2~3 inserts before it mounts. I've done PRAM & PMU reset, same results. Is my drive failing?

I can view the same disk/photos on my old L300
There are any number of special so-called packet writing programs which create discs readable only by the same program. If you use the built-in DVD burning for Windows Vista (especially with Mastered format), that problem would not occur.
Burn a CD or DVD
So you should either reburn the DVDs using the Vista machine or copy the pictures to the new machine (probably over your network) and burn new DVDs from there.
When you post here, always tell us the full model designation of your computers. Which Satellite Pro L330? Which Satellite Pro C660? That way we can look up what your machines look like.
