Superdrive Should Read Dual Layer, but doesnt?

I recently purchased a Powerbook 17" and under the specifications, it is supposed to support Burning Dual Layer DVDs. However, upon looking under my System profiler it does not show this. Why?
MATSHITA DVD-R UJ-835E:
Firmware Revision: GAND
Interconnect: ATAPI
Burn Support: Yes (Apple Shipping Drive)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media:
Type: DVD-RW
ID: CMCW02
Here are the specs. I would think that an 835 should support DL, it should be one of the newer drives. But I do not know. Can anyone help?

I believe only the last version of the 17" G4 PB had a DL burn capable drive. Exactly what model do you have? Your System Profiler specs indeed do not show DL capability.
You may get more info in the proper G4 17" forum - this is the 15" forum.

IBook read dual-layer DVDs?

Does anyone know if the iBook G4 1ghz or higher can read dual-layer DVDs? Thanks.

Do you mean home made dual later DVD-Rs or commercially pressed DVD movies that are dual layered? The answer to both should be "yes". However, the software used to burn a home made dual layer DVD-R may or may not be compatible with a Mac...

Read Dual Layer DVDs in Mac Mini 2005

My brother has a Mac Mini that he bought in late 2005.
Can he read dual layer DVDs in this optical drive? More specifically, can he use Handbrake to rip dual layer DVDs on this Mac Mini?

Might be my ignorance speaking here, but this is the first I've ever heard of a drive that won't read a dual-layer disc. The vast majority of commercial DVD movies are in DVD9 (DL) format, and I'd be beyond surprised if your iBook wasn't able to play any of them...
I don't have my iBook yet, but I'd guess the combo drive in my Mini is the same, and I've yet to find any DVDs that won't play...

Problem with reading Dual Layer DVDs.

I've a normal iBook G4 with a combo drive (it's the 1 Ghz model) and when I insert a dual layer dvd which I've made on another computer at school, the drive in my iBook won't read it (as in it spits it out). I was wondering if this problem extends to everyone else with a similar model/drive.
The media I used is a TDK DVD+R dual layer disc. The drive has had a problem reading a dual layered DVD-R; the problem being that it could only read (possibly) only one layer of the disc.
Is there a firmware update that can applied to rectify the problem?

Hi and thanks for your reply.
I'm actually not sure if I can read commerical dual layer DVDs, but the fact that the DVD was pressed and not burnt, and that the DVD is released for commercial purchase has lead me to believe that my drive can read the DVDs.
Also backing up my drive's ability to read dual layer DVDs, as mentioned in my previous post, is that it could read parts of a DVD-R dual layer DVD. What I meant by parts, or, just one of the two layers, is that the dvd contains a folder which houses 4 gigabytes of data, or about half the DVD. The contents within this folder can be copied to the hard drive, whereas the content on the root of the DVD can not, causing the drive to continually spin the disc, making the "trying really hard to read" noise, forcing me to restart the computer whilst holding the mouse button in order to get the dvd out.

Can powerbooks read dual layer discs

can my powerbook read dual layer discs? 2003 867 mhz reads cd's and burns cd's and reads dvds

The last 15" and 17" 1.67Ghz Powerbooks released can read and write double layer disks. Prior to that, no. Last PowerBook specs are at http://support.apple.com/kb/SP38

Macbook Pro doesn't seem to read Dual Layer DVDs

I was trying to restore my laptop using the original restore/install dvds that came with it. When I slip the installation discs into the optical drive, my Mac doesn't seem to read them; it just ejects them.
But I tried inserting audio CDs, data DVDs (4GB max in size) and they seem to work and recognized by my mac. My mac doesn't recognize the installation discs only. I have even went the extra mile of purchasing another Snow Leopard installation disc and the disc, which is sealed, new and fresh from the store also got ejected by the machine. I have read somewhere that the installation discs are Dual Layer DVDs. Seems like my optical drive is not reading dual layers discs anymore.
Any advice how I can mitigate this? Are there any firmware updates that I can upgrade or downgrade to? How will I know which firmware my optical drive is running on?
Thanks!

You can reset the SMC and see if that helps. If it's a unibody or Retina, follow the method for "a battery you should not remove yourself."

Combo Drive reading Dual Layer / booting from external DVD USB

I am helping a friend with an iMac G5. He has the combo drive which is not able to read the dual layer Leopard DVD. I have looked to see if there is a firmware update for the drive however no luck. I am able to put an external usb DVD and it reads the disk however I was not able to boot from the disk using keyboard commands I tried AppleOption+ShiftDelete, C, and also tried Option but no luck.
I have been reading that booting from usb external drive is a no no on older G5 iMac's unless you are using fire wire. If any one can give me some help with getting the USB drive to boot, or figuring out why the combo drive spits out the DVD every time I would appreciate it. I am also willing to make a bootable usb leopard thumb drive, but I don't want to waste my time if it's not going to boot from USB.
Thanks,
jtadmin

Do you happen to have a more recent Mac that can read the Leopard installation DVD?
If so, you may be able to start up your Mac in FireWire Target Disk Mode,
http://support.apple.com/kb/HT1661
and let the iMac G5 use your Mac's optical drive to boot from the Leopard DVD.
Also, it is true that PowerPC Macs can generally only boot from external drives that are FireWire.

Can iMac read Dual Layer DVD+R???

If I use Toast to backup my G5 tower data onto a Dual Layer DVD+R disc, will my iMac Flat Panel be able to read it? I've heard that some older drives can't recognize the Dual Layer DVD+Rs.
Anyone tried a home made dual layer disc on this model iMac yet?

These are the formats supported in the iMac G4.

Welcome to Apple Discussions, humain.
I have been burning DL DVDs from another Mac for quite some time now. Never had any problems with the DVDs being unreadable on my PowerBooks except when there was a bad batch of discs, which then meant only the Mac that burned the disc could read it.

Matshita UJ-825 - Unable to read dual layer DVD+R

Haven't had any issues with my Matshita UJ-825 until now. Have a DVD+R DL full of photos, but the Matshita will not mount it. When I insert the DVD it sounds like the drive is working to mount it and then just spits the DVD back out. What's really strange, a co-worker has the same UJ-825 in a 12" Powerbook and he can mount the DVD, no problem. The only difference is his UJ-825 has firmware revision DAM5. Here's the specs under "System Profiler" for my drive:
Firmware Revision: DBN7
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
I've read through A LOT of discussions similar to my problem, but none seem to have any answer. Thought I might try my luck. Any help is appreciated!
iMac G5 Mac OS X (10.4.4)

I understand some people think "googling" is the end-all solution to finding resolution on certain issues. But, I wouldn't have posted here if I hadn't tried searching on Google to begin with.
On that note, does anybody have other ideas beside searching Google?
I know that Matshita is a part of Panasonic, but a search there turned up nil, as well.
Anybody know if it's possible to copy the firmware from one Matshita and then somehow flash another Matshita with that firmware?

Trying to read a file but doesnt know how to get the size of the inputstrem

hi im trying to read a file in a cel this is my code:
fconn = (FileConnection)Connector.open("file://localhost/" + actualdir);
InputStream fis = fconn.openInputStream();
byte b[] = new byte[1024];
fis.read(b);
fis.close();
fconn.close();
textBox1 = new TextBox("Viendo el Archivo: " + list1.getString(list1.getSelectedIndex()), null, 1024,TextField.ANY | TextField.UNEDITABLE);
                          textBox1.setString(new String(b, 0, b.length));                        i dont want to create always an array of bytes of size 1024 instead i wanna know how many bytes does inputstream object has, how can i know that?

you can either retrieve the whole file at once by determine the file size like:
fconn = (FileConnection)Connector.open("file://localhost/" + actualdir);
InputStream fis = fconn.openInputStream();
byte b[] = new byte[fconn.fileSize()];
fis.read(b);
fis.close();
fconn.close();
or read every single byte
fconn = (FileConnection)Connector.open("file://localhost/" + actualdir);
InputStream fis = fconn.openInputStream();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int i = fis.read();
while(i != -1){
baos.write(i);
fis.read();
String content = new String(baos.toByteArray());

Can my Combo-drive read Dual-Layer DVDs?

I have a Combo drive in a PBG4 12" 1.33GHz with a combo drive. Can I read DL DVDs burned from one of the new Macs? I couldn't find any litterature on this.
Thank you!

Playing dual layer dvd's with iBook superdrive

I've burned a couple of dual layer DVD's (8.5GB) with my iBook G4 and an external Lacie DVD burner.
I used Toast 7, experiencing no problems at all.
The DVD's play perfectly using the Lacie driver itself, or my Sony DVD player, or even a 10-year-old Pioneer DVD drive on my PC.
But... my iBook Superdrive refused to even read them.
The disk just makes a couple of turns and then the superdrive ejects it with no message.
The superdrive plays perfectly the commercial dvd's, which I know are usually double layered.
Does that mean that superdrive is not compatible with burned dual layer dvd's?
iBook G4; iPod 60GB v1.2.1; iTunes 6; Airport Xpress Mac OS X (10.4.4)
iBook G4; iPod 60GB v1.2.1; iTunes 6; Airport Xpress Mac OS X (10.4.4)

I don't believe the SuperDrive for the iBook is set
up to read/write the dual layer DVD's.
I didn't expect it to write DL DVD's, that's why I used an external burner.
The problem is when reading the burned dvds
Go to your Apple Menu and select "about this mac".
Click on the "more info" button and navigate to the
Disc Burning label. Select it.
If your SD is dual layer compatible you'll see "+R
DL".
It says generically that SD reads DVDs
What speed were you burning the Dual DVD's on the
LaCie?
don't know, really, but Toast is set to burn disks at the best speed:
one was a DL DVD+R 8x, the other a DL DVD-R 4x
it's IMPOSSIBLE that SD can't read dual layer DVDs: commercial DVDs are 6-7GB, they MUST be DL and they play perfectly.
and if it really can't play burned DL DVDs, that's really a shame! >:-Z

Problems with dual layer DVD reading MBPro (2009)

Hello,
recently i wanted to take a look at a dvd that came with a magazine (for pcs, but that shouldn´t really matter here) on my macbook pro from mid 2009 (see http://support.apple.com/kb/SP541) with the latest version of osx.
Unfortunately, it didn´t succeed to read the dvd. only ejected it after doing a little searching and making strange noises.
According to the technical specifications this macbook pro should be able to at least read dual layer dvds. I won´t even try to burn one of those, because after doing a little research on the www i found a lot of entries with people going insane with the burning capabilities of macs concerning dual layer media.
Unfortunately i couldn´t find anything on the topic in the forums here. Also no official statement whether macs can or cannot cope with dl media. In my opinion, if it´s specified in the tech specs, then the computer should also live up to the expectations.
Are there any suggestions on how to go about with the matter of dl media and macs? Any information would be much appreciated. Also a notice from apple would be nice, this seems to be a matter (given, although probably not of top priority) concerning quite a lot of people and machines.
kind regards,
Reinhard Sommerer

Hello again,
well - thanks for the information. i would like to point out that the dvd i was trying to use was not for burning purposes. it was a medium that came with a magazine. out of my experience sometimes these work even better than home-burnt dvds, but that might be subjective.
anyway, tonight i gave it another try with the cleansed medium. apx. in the same condition as last time (had stored it in a safe place) and big surprise: this time it didn´t read neither side again. kind of a drawback - maybe tomorrow i´ll have more luck again.
so my hopes for an apple official to comment on this forum won´t be heard, i guess. although it appeared to me that last time here i had seen a user profile resembling an official apple profile. but i might be wrong, i´ll just keep on wondering about this so-called dl-drive.
kind regards,
reinhard
