Trouble reading DVDs

I am not sure if there is where I ask this question. I have to locate a photo that was taken last year. I have all my photos (jpeg and mostly RAW) backed up on DVDs. I did this when I had a PC. Now when I put the disc into my computer it says it cannot be read in this computer. When I put them into my notebook (Sony Vaio) they come up fine. I was planning on selling the Sony to get a Macbook. Does this mean I will have no backup of all my photos that I can find on a Mac? At this pioint I am very worried. Happy New Year everybody!!!

The burning was done with Sonic Now (it came with the HP computer). The images were burned as soon as I put them into Lightroom before any editing was done. This was to be my backup for an emergency like this. Surely other have burned DVDs on a PC and been able to bring them up on a Mac. What happens from now on? If I burn on this Mac I am working on will the photos not be recognized in a PC? When I spoke to the fellow at Apple when making this change - he said no problem it would read my backup DVDs. A great deal of the thousands of photos are NEF RAW. Thanks for any info you can give me.

New MacBook Pro has trouble reading DVD

Our new MacBook Pro will not automatically open a DVD when it is inserted. Had to go through DVD player and it said it did not recognize format. Had to manually select the app for it to play. DVD player is 5.1.1. Is this a bug? Linda

One DVD or all? Commercial DVD? One you burned? One you found lying on the street? More details would help...
Assuming you mean this occurs with multiple (all) commercial DVD movies, go to System Preferences > CDs & DVDs and set the 'When you insert a video DVD:' pop-up menu to Open DVD Player.

Trouble reading DVDs on macbook.

My macbook is able to read and burn DVDs, and I have done it in the past, but for some reason now it won't read any of the DVDs I try. When I put the DVD, it sounds as if it's trying to read it, but then the computer spits it out. I tried it in a Macbook Pro and it mounted just fine. What could the problem be? Thanks.

Can not burn or read dvd/cd's on imac g4 flat panel

Hello
Just recently I am having a great deal of trouble burning dvd's or cd's. If I manage to get a dvd or cd to burn(which is very rare that I do manage to get them to burn) they will no longer mount on my computer after I have ejected them from the computer. I get the same result wether using toast or the Disk Utility. My local Apple reseller sugested the drive was ok but had a coruption in the software. So I did a full and complete wipe of the system and freshly re-installed teh whole system. I am still getting the same problem.
The error messages I'm getting are "medium error xxxxx" or can not calibrate lazer level.
I have cleaned the dvd drive and I have made sure all disks are clean before using.
So any help would be appreciated.

check out the screen I get when I hold command at startup, what does this mean? none of the keyboard buttons respond to this or the mouse, except the return key which brings me back to the grey screen hanging forever.

Drive keeps ejecting Blank DVDs but will read DVD with media in it

I am at loss what to do. Whenever I put in DVD with media in it (including +R), it plays and reads it all just fine. CD data reads no problem too. However, when I put in a Blank DVD, it chugs and ejects it out completely.
Preferences are fine. It says 'Ask What to Do' is set when 'You insert a Blank DVD'
Here was how it started. Previously, I could put in a blank DVD and it would be just fine but I'm having problems burning after the 10.5.6 update. Read in a post somewhere to try resetting your PRAM which I did and now it won't accept the blank DVDs. Everything else is fine.
Would really appreciate ANY help I can get!

Itunes won't read dvd

My itunes does not recognize my cd.(Pink-Funhouse)I am trying to rip it to add to my ipod but it says no cd in computer.Help

The subject line says that you are having trouble with iTunes reading a DVD (not surprising as iTunes doesn't read DVDs). However, the body of you post says that you're having trouble with a CD. Can you clarify?

Trouble burning dvd...message: playback may be disabled

i'm having trouble burning dvd through - share - then checking blue ray box and burning it as AVCHD. i've done it before by following these same steps but this time the dvd player gives me the the playback mabe be disabled message, any suggestions...

no, i'm not trying to burn a blue-ray disc, it's just a box in a burn window that you check even when you're burning regular dvd, so it'll come out as avchd. anyway for some reason i can't get it to work.

Trouble playing DVD-ROM games...

Hello, I'm new to Macs and my 1.42 GHz iBook G4 is less than two months old. A few days ago I purchased the Myst 10th Anniversary DVD collection, and all three games have been running incredibly slow. The first two games run under Classic mode, and the last one runs native to OS X. When I try to play the games from the disc, my iBook's Superdrive makes a loud sweeping sound, like it's having trouble reading the DVD. When I try to play the games by copying all of the video and resource files to the hard drive I get very sluggish video playback and transitions. I know this isn't a problem of insufficient hardware because these games are five to ten years old and the highest system requirement is, I believe, a 400 MHz G3.
I have been able to read, rip, and write other CDs and DVDs so I'm not sure why my Superdrive would be acting up so much with these games. Should I contact Apple about this problem?

Must be a problem with the game itself, as I've gotten other DVD-ROMs to work.

Trouble erasing DVD+RW

Has anyone else had trouble erasing DVD+RW media (or any rewritable media for that matter)? I have been trying to recycle a disk that I used to store iPhoto pics on but Disk Utility would not erase it. It pretended to do so then when I re-inserted the disk it still had all of the original data on it. I tried Quick Erase as well as Full Erase with the same results. I then tried erasing a CD-RW and ran into the same problem. Nearly exasperated I tried it with the CD-RW again and it worked. I backed up some iPhoto pics to the CD-RW then I figured I would try the DVD+RW again. Miraculously it worked this time.
Does anyone have a clue as to what might be happening?

What dvd burner do you have???

Reading DVDs

I know similar issues have been discussed and have read those discussions, but my problem is slightly different.
I have the combo drive and have been unable to read user burned DVDs (I burned some DVDs on another computer). Commercial DVDs work fine, and I've had no trouble with any kind of CD. Is the combo drive generally unable to read burned DVDs or does this sound like an issue of reading certain blank media?
Just prior to having this problem I had reinstalled OS X due to some hard disk problems--so all permissions had been repaired recently.

It probably reverts back to the statement you made. ( I burned some DVD's on another computer).
What other computer?
What software was used to burn?
What Format Disc's were used to do the burn?
All or any one of these can affect your ability to read burned media.
If your combo drive is only capable of reading DVD-R Media then if you put in + or RW Media then there is your problem.
If you burned the DVD on a PC and the software was set to PC only, there is your problem.
Many of the Software on the market give the options to burn and be for PC only, Mac only, or PC & Mac compatible.
I realize that in a perfect world you just put in any media, and it will read and write it. Sorry it isn't the case.
Try to use DVD-R Media, it is the most widely recognised.

I have trouble reading in Black and White. changing the background color for all

I have trouble reading in Black and White. On my PC I can change the background color (and I am not just talking about for a word or pages document) but for eveything so anything that was a white background I can put in what ever color I like but it still prints in Black and white.. I can't see how to do this on the Macbook air. on my PC I do this in display. Sort of putting colored film over the screen I dont know what to do. Can anyone help?

Hello Floridamacbookpro,
You may be interested in the 'invert colors' Accessibility feature. This can be invoked by pressing the Control, Option, Command, and 8 keys on your keyboard. This only affects your display, and does not have any affect on printed items.
Mac OS X displays inverted image colors (white on black, reverse type)

Running a mid 2009 iMac on 10.7.5, 3 gb memory, 320 gb hd.
Suddenly the computer stoped reading DVDs and the only time I can read a CD is if I restart. Quite often when I insert a CD it gets stuck and I cannot get it out until I restart and it shows up on the desktop where I can then eject it.
I have checked and double checked the finder prefs and all looks normal showing a check mark on CDs,DVDs etc. (the ones I want to show up on the desktop)
I have reset the PEAM, repaired permissions with both the disk utility on the computer and the disk utility when I start up in the Recovery Disk. I did notice that sometimes the permission repeat the same correction several times before it moves on, and sometimes it doesn’t. I have Windows installed on a partition but I keep it unmounted until it is needed for my wife’s work. The dock seems to be just fine and all the apps seems to run just fine. When I insert a photo CD iPhoto does not open but when I insert a music CD iTunes does open.
Also, most every time I open iPhoto it takes a long time(sometimes as long as 2 minutes) for it to load.
Sometimes my Mail (Mail 5.3) does not post new mail but most of the time it does.
Once and a while it seems like the computer slows way down but then it seems ok ten minutes later.
All of these ‘things’ seemed to have happen suddenly and I have not downloaded anything from the internet in some time.
Of course the warranty and extended warranty are both no longer in effect having had this computer for more than three years.
I am running Java and Adobe Player because some of the sites I go to a lot require both.

I believe that insufficient RAM may be the source of some of your problems. If you have a RAM of somewhere 4 to 8GB, you will experience smoother computing. 3GB doesn't seem right, so you might want to learn more by going to this site:

I don't know what know what's happening with your optical drive, but it seems you use your drive quite a bit. In that case, look into a lens cleaner for your machine. It's inexpensive, works quite well.
I hope you'll post here with your results!

Odd problems with reading DVD media [concluded]

There is an odd problem I've encountered...(I'm not sure if its a bug with Arch Linux or Linux in general).
Firstly, the details:
* I've updated the systems (using "extra", "current", and "community" respositories). So its the current one (0.80 "Voodoo"). I'm NOT using "Unstable" respository.
* I've already added the user to the "optical" and "storage" groups. So there's no problems in relations to permissions.
* My fstab entries for the CD and DVD drives are default (I didn't touch them)...That is, "iso9660" and "udf" respectively.
* My desktop environment is KDE 3.5.5...And I have changed the behaviour of the desktop icons such that DVD media, CD media, and USB devices will have an icon pop-up as soon as you plug them in.
* I have "hal" loaded in the DAEMONS of /etc/rc.conf
* I'm using 4 different Linux systems with the following DVD burners.
=> Pioneer DVR-108
=> Sony DW-Q120A
=> Hitachi-LG GCC-4240N (DVD-ROM/CD-burner combo)
* There are three Sempron 2800+ (Socket 754, 1.6Ghz) boxes and the last one is on an IBM R40 ThinkPad, and I know you can't read DVD-R media on that. But it should be able to read DVD+R media without issue.
* Two of the Semprons are running Arch, as well as the ThinkPad. The final Sempron box is running Ubuntu 6.06.1
* When I installed K3b I did: pacman -S k3b dvd+rw-tools
* All the DVD media is Verbatim DataLifePlus ones.
Here's what I've done...
I've burnt two DVD media (they're just video files from last year's Blender 2006 conference thing, so its legal stuff).
One is a DVD+R and the other is DVD-R media. Both were done on a Windows 2000 Pro SP4 box using Nero 6.6.1.4
What's the problem?
Well, KDE in the Arch Linux boxes doesn't recognise the media!...There is no DVD icon that automatically pops up on any of the Arch Linux boxes!
When I run dmesg on the Arch boxes, the only relevant info I get is:
ISO 9660 Extensions: Microsoft Joliet Level 3
ISOFS: changing to secondary root
Now if I re-insert these DVD media onto an Ubuntu 6.06.1 LTS box...The DVD+R works perfectly! While the DVD-R does not.
When I run dmesg on this box, I get the following:

If I re-burn the data onto a DVD+RW, Arch and Ubuntu immediately sees it, and KDE (or Gnome in Ubuntu), will have a DVD icon popping up! I can view the video clips without issue!
Now here's the really odd part...
When I load up K3b on either Arch OR Ubuntu, they recognise all DVD media! (As in, they can read the media disc information!)...Tools => DiskInfo
If I click on the PIONEER - DVD-RW DVR-108 on the tree menu on the left side in K3b, (to view the contents of the DVD-R or DVD+R media), it can't read and pops up an error message informing about a read problem. It suggests I try dmesg|tail to see what's wrong.
When I do that, I get...
# dmesg|tail
grow_buffers: requested out-of-range block 18446744073708569376 for device hdc

grow_buffers: requested out-of-range block 18446744073708569376 for device hdc
UDF-fs: No partition found (1)
I repeat the same procedure on DVD+RW, and it works perfectly!
Should I use another burning application instead of Nero on the Windows box?
Could it be the way I burn things?
(Some DVD+R and DVD-R are burnt with multisession while others aren't.)
Has anyone else experienced similar issues?
What are your "workarounds" or fixes?

It *should* work...But they don't.
I tried this...
mount -t auto /dev/dvd /mnt/dvd
I get this...
mount: block device /dev/dvd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/dvd,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
I then do dmesg|tail
grow_buffers: requested out-of-range block 18446744073708569376 for device hdc
UDF-fs: No partition found (1)
If I try this...
mount -t iso9660 /dev/dvd /mnt/dvd
I get this...
mount: block device /dev/dvd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/dvd,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
I then do dmesg|tail
Unable to identify CD-ROM format.
If I stick in a DVD-R that is burnt in one go without multisession, I get this in the dmesg
UDF-fs: Partition marked readonly; forcing readonly mount
UDF-fs INFO UDF 0.9.8.1 (2004/29/09) Mounting volume 'SW', timestamp 2006/11/07 19:37 (1000)
It reads this disc perfectly and KDE pops up a DVD icon.
I'm scratching my head as I'm not sure what is the problem.
Could it be hal or the way the DVD media was formatted?
