Will burning an encrypted disc image result in an encrypted disc?

I searched for this all over and was surprised that I couldn't find a thread from later than 2002. Basically, if I put some files in a disc image which I've password-protected (in Disk Utility), and then burn a disc from that image, will the resulting disc be password-protected also? If not, does anyone know of a similar or equivalent procedure that I could use to back up sensitive data?
Many thanks,

You need to distinguish between using a disk image as part of the creation of a disk, and burning the image to a disk. Some people use DU to make an image, then mount that image and essentially just burn the files to a disk. Alternatively you can burn the image file itself to a disk. It's the image file that is encrypted. So if you burn the files that are on the image to a disk they are not encrypted, but if you burn the main disk image to a disk and then try to open that image it will require a password.

How do I burn a disc image (img file) to dvd?

I created a disc image from iDVD, but my disc drive on my home computer is broken. With a flash drive, I copied the img file onto my work computer & burned the file to disc. However, while the file copied, the disc doesn't play as normal dvd. What am I doing wrong? Thanks.

Though the replies above were very helpful and most likely would have worked, my work computer doesn't allow access to Disc Utilities. However, I bugged my IT guy and he showed me another way, using the Burn Application. I just needed to use the correct setting, as was mentioned above, I was burning data & not DVD. I'm sorry I don't have it in front of me, but I think I had to click the DVD tab & then select DVD/Video from the drop-down menu. One quirky element: I wasn't able to drag/drop the img file into Burn. I needed to drop the contents of the img file (the VIDEO_TS folder). Then it worked fine.

Lose audio when burning to disc image.

Hey guys. I am losing my audio half way through my project when I play it on a dvd. My audio is there after I export to quicktime, but when I create the disc image through iDVD and burn through Roxio toast my audio is only there toward the first part of my project. The video portion is fine though. Any thoughts on this would be great .
Thanks,
D.T.

Burning a disc image and copying it to disc is the recommended workflow around here -- it is one more action that you have to initiate, but it provides greater control (set the burn speed down to 1x or 2x) and it is less demanding on your computer (fewer errors?).
Re the audio -- if the music was purchased from iTunes, you may be caught up in a problem that should have been resolved in iLife06. There's a workaround (burning a CD from iTunes and re-importing) but provide some more details on the audio.

Automator problem parsing variable as filename in disc image

Dear apple/automator forum.
I have just recently started using Automator, and i am experiencing a little problem which im hoping to get a helping hand with.
First, heres my screenshot (sorry its in danish, ill explain what iwe done): www.bergsorensen.dk/screenshot.png
- As for text
- Set new variable
- Get finder items
- New disc iamge from finder items (variable as filename)
I made a service which creates a new disc image of the selected finder items. Now, "in front" of that, i wanted a dialog box, where you could type the name of the new disc image - filename.
The creating disc image flow works perfectly, though i cant get the dialog box to parse the variable as name to the disc image.
Any suggestions?
Best
Kasper

You might want to update your forum settings, since your screenshot indicates you are running *Snow Leopard's Automator*.
The problem seems to be that you are mixing the text from your dialog with the input items - note that any selected items are already passed to the service, so you don't have to use additional actions to get the input. You just need to add a few actions to save and restore the original input when getting your other variable(s):
1) *Set Value of Variable* { Variable: _Original Input_ } -- save the input items
2) *Ask for Text* ( *Ignore Input* ) -- get a name for the disk image
3) *Set Value of Variable* { Variable: _Image Name_ } -- now we can use this variable in other actions
4 *Get Value of Variable* { Variable: _Original Input_ } ( *Ignore Input* ) -- get the input items back
5) *New Disk Image* { (drag _Image Name_ variable to the "Volume name" and "Save as" fields) }

Burning disc image with encryption

I've been burning disc images thru idvd's interface for a while. I just noticed in disk utility the option of encrypting the dvd (AES-128), to prevent access to contents, files, etc., which might be useful when making customer copies.
Is this something anyone is using?

Are you referring to data dvd's?
To the best of my knowledge, Data Dvd's may work well on your mac but they do NOT play back on most set top dvd players.
It is possible to encrypt data to a dvd BUT it is Not possible to encrypt an entire iDvd (at least not in terms of preventing duplication /playback on a standard Dvd Player/recorder) in the same manner as a commercially pressed DVD function which are copy protected (CSS) when mass replicated.
They are two entirely separate forms of encryption.

Problems burning DVD from iDVD disc image

I'm burning a disc image onto a DVD using Toast and can't seem to get the disc to automatically start or be read by either my home DVD player or my Powerbook G4 (through DVD player). I'm a little unclear if I burn the .img folder onto the DVD, the mounted drive containing the AUDIO_TS and VIDEO_TS files, or the AUDIO_TS, VIDEO_TS files themselves. I've tried all of these and none have worked, which made me think that it was something wrong with my DVDproj file from whence the disc image was made.
Do I have to have something in the box labeled "Drag content here to automatically play when disc is inserted" in teh MapView? I'd prefer it to just bring up the DVD menu.
Thanks!

Pre edit:
Suggest you create a disc image and then burn the DVD. File/Save as Disc Image...
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
There are variations to this process based on which OS X you are using...
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (maybe the .img) in the left-hand window. Click the Burn icon. A new window should drop down and your SuperDrive tray will open after clicking the Burn icon. Insert a recordable DVD. (Verbatim DVD-R preferred by me.) Click the Close button. Wait. Select a burn speed. If you hold your mouse cursor over the pop-up it says: "Select a slower speed to work around burn failures," so select 4x or slower for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk to check your iDVD project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD Media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

Burning from disc image: do I mount it first or not?

I'm sure this is a dumb question, but I don't want to waste my few remaining Apple DVDs testing the two options. I made my home movie into a disc image because I needed to use the professional setting to make a longish movie fit on a single-layer disc. So now I want to burn it. iDVD '08 says to do this from within Disk Utility. But nowhere can I find out whether or not I need to mount the disk and burn the mounted disk so that just the audio_ts and video_ts folders are on the DVD or whether I should burn the file that ends in .img directly to the DVD instead. I'm confused. If somebody could just walk me through the steps, I'd very much appreciate it. Please assume total ignorance.
Many thanks for any help,
WA

The resulting disk should play in my parents' DVD player?
Just a suggestion...... You can take it or leave it (your choice).
If I were burning an image or making a Dvd copy for my in-laws to play on their Sony set top dvd player as opposed to a mac, I wouldn't use the Finder nor apple's disc utility (not that either approach won't work .... most of the time it will).
It's just that I get slightly better (if not more predictable) results with Roxio Toast to burn the image to Dvd-R while lowering the burn speed to 4x or lower and using quality media like Verbatim or Maxell.

Disc Image will not mount after format

I am trying to create a disc image from DVD Pro so that I can burn the final project at a low speed to avoid burn errors. Whenever I try to burn the image to DVD in Disc Utility it says that the file is not recognized. I have even tried to start the project from scratch and still am getting the same error message. Another weird thing that DVDSP is doing that is odd is when I am build and format, the log shows a ton of error messages saying that random files will not be included on the final DVD. Please help, I cannot figure oout what I am doing wrong.
Thanks,
Leon

Leon:
Warning: The file ‘2007KIAC_BBTOURNY.layout’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
Warning: The file ‘VOB_DATA.LAY’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
These are standard wraning. Nothing to take care about.
After deleting the old build empty your trash and try again. If DVDSP ask to reuse, you must be building to another location than where you think. Check that.
Hope that helps !

Burning From a Disc Image Problems??

I recently purchased iDVD 5. The best feature in the new iDVD for me is the ability to save my projects to disc image which lets me keep just the disc image on my hard drives with a file size of roughly 3-4 GB. This saves me a TON of space as I was having to save all of the self contained movie files along with the DVD projects in order to burn more copies for my clients in the future.
My concern is that burning these extra copies of my projects for my clients with disk utility is not as "solid" a way to create DVDs as it would be to simply burn all the copies I may need directly from iDVD.
Is this true?
Also, I have never been able to verify any disk that I burned from a disk image using disk utility. These disks play fine on my new Sony DVD player, but I have had some complaints from clients that the disks skip and don't play perfectly.
What could be causing this problem?
If I can play these disks on my home DVD player even though my computer can't verify the burn, should I be concerned?
Is the inability to verify a problem with my burner?
Pete

Len,
Others have had the verify "problem." I NEVER verify.
Really? Then I don't need to verify? My burning process goes to this automatically, I think. How do I stop it?
BTW, I did install Tiger, no problem, installed FCE and made a very short movie, only one transition, no added audio, but burned with iDVD just great! It takes some adjusting, but I am getting the hang of it, and it hasn't been too hard to learn yet
I think I will use iMovie--> for my photos/videos to DVD projects for a while, but when I get to mostly videos and all digital photos, I think I will go back to FCE (or whenever I have lots of time to be REALLY creative)
PS. I'm SURE you ARE younger than I am! I'm like Old Toad...we're older than dirt!

Burning from disc image

Trying to replicate a DVD for which I no longer have the iMovie files - successfully created a 3.44Gb .dmg file, BUT when trying to burn from this, I get "buffer underrun" messages. There is >17 Gb free space on the hard drive. Also, I am unable to copy the .dmg file to an external drive with 18 Gb free space as after about 2Gb it fails with an error message that the drive is full. Something funny about that disc image file?

I am using Disc Utility as per those directions, and this has worked with no problems on similar DVDs.
I also suggest you get the free download Mac Sweeper which you will find on http://mac.softpedia.com/get/System-Utilities/Mac-Sweeper.shtml
Then:
1) Shut down/Restart without any applications running.
2) Run Mac Sweeper carrying out all the optimize options including repair permissions and, under clean, empty caches.
3) Now do your disc copy with nothing else running.
Onyx will have the same functions as Mac Sweeper. This is a bit of an overkill but it will give your system every chance of a trouble free burn.

Error when burning disc image

An error occurred when I tried to burn a disc image of a DVD slideshow. The slideshow has 324 slides in it and is almost 38 minutes long at the moment. I have added sound by creating a sound track in iMovie using a combination of songs downloaded from iTunes and tracks from my own CDs then blending the two blending the two. The slideshow plays on the computer and I have burned a disc image two or three times as I was creating it.
Any advice?

I have burned a disc image two or three times as I was creating it.
Can you clarify what you did exactly? You mean you saved the project as a disk image, then went back and did further work on the project?
The audio tracks you imported from iTunes may have been copy protected and will not burn in iDVD. The workaround is to burn those tracks to an audio CD in iTunes, then re-import into iTunes from that CD. Then will transfer to iMovie and iDVD without problems.
Also, something here may help:

Having problems burning/creating disc image in iDVD 6

I am currently experience new problems trying to burn or create a disc image in iDVD 6. I have successfully burned iDVD projects in the past with the same computer/iDVD 6. The iDVD project looks like it is processing normally, even creates a labled disc image- but when you click on it, it reads "My Great DVD", and the video and audio files are also unreadable or absent- the error message for the VIDEO_TS.VOB file I pulled up read, "There is no default application specified to open the document "VIDEO_TS.VOB".
My older son just got Toast 7 Titanium for me, so I have that resource. I also just bought extra memory to bring me up to 1.25 GB, and an external hard drive with 320 GB. I have a younger son and a friend who will need me to make a dance audition DVD for a CA college dance department that must be in So Cal by 1-19-07, so you can imagine I'm getting a bit nervous about this. I have verified permissions, reinstalled iDVD from the original, and re-done the original iMovie/iDVD project that first caused the problems- a 12.8 GB project (but have not re-done things since I got more memory on my computer). I don't know how big the audition DVD's will be, but estimate they won't be that big (hopefully), but will consist of many short clips/chapter headings. I know just enough about computers to know what I don't know, so would really, really appreciate some basic help!

My Great DVD", and the video and audio files are also unreadable or absent- the error message for the VIDEO_TS.VOB file I pulled up read, "There is no default application specified to open the document "VIDEO_TS.VOB".
I don't know what you expect. You're looking for a problem where there isn't one.
The AUDIO_TS folder SHOULD be empty and (unless you've installed spercial software) you WON'T have any application to open the VIDEO_TS.VOB.
If you want to play the disk image, open Apple's DVD player application and then use it to open the VIDEO_TS folder.

Burn error (disc image)

All of a sudden, iDVD 5.0.1 won't burn a disc image. Gets to some point through the process (might be half way, might be right through), then says, "Burning completed. Some errors were found during the burn process". Doesn't create any file at all. Have tried buring a few different projects, with the same result.
Any clues?

I am having exactly the same problem. My iDVD project started in iPhoto as a "saved slideshow". I have followed all of the steps as provided in two 3rd party manuals -- Jim Heid's "iLife '05" and David Pogue's "iMovie and iDVD 5 -- the Missing Manual". I have even done a "Project Archive" file as the basis to burn the iDVD to ensure that all the resources are together and available. My project consists of a 24 minute slideshow comprised of 230 photos all with "Burns Effect" panning and zooming and with a background music track. This was sent to iDVD from the iPhoto commands. The "Memories" theme was applied with text modification, changes to the font style text location and color, and changed audio selection. A second slideshow was added which consisted of an archive of all the photos used in the original, plus some added ones that were not used. This added a second button on the main menue with three sub-menues on a secondary menu, where the photos were automatically broken down by iDVD into three groups of photos of less than 100 each for a total playing time of approximately 6 minutes (1 sec per photo). The project was then saved and archived. Everything plays fine up to this point. The total memory of the saved archived project file is 2.86 Gb. The rendering and processing time for iDVD to create the disk image (.img) file exceeded 5 hours. I've tried to generate the disk image three times. Like Jim White, in one case after nearly 3 hours, the program put out an error message saying that errors had been encountered and the processing was being aborted. In the two other cases, the processing went the complete 5+ hours; gave a message that the "burning was finished, but that some errors had been found (on verification?) and produced NO FILE.
I am using a Mac G4/1.25 Ghz MDD , Mac OS-10.4.2 with 768Mb RAM and 13.5 Gb of available hard drive storage at the beginning of disk image processing; with iPhoto 5.0.4 and iDVD 5.0.1.
I have no experience with earlier versions of iDVD, so I can't say if this is a problem created by the 5.0.1 update, or the upgrade to Tiger. In any case, this is extremely poor error coding, especially considering the amount of time required for the image processing -- i.e.to state after 5 hours that an error was found which aborts or invalidates the burn without providing any clue as to what or where the error was -- this makes the entire software package of virtually NO VALUE.
Your comments, please!

No imports while burning a disc image

While I am burning a disc image in iDVD I am trying to import a movie to iMovie through a DV box. While the disc image is burning, iMovie will not pick up the box, or any imports. When its done burning, iMovie goes back to detecting the box. Anyone know what this is???

I'm curious... What happens if you start the download first, before you start burning the DVD?

Burning DVD from disc image

I've been burning DVD's from disc images using Encore 1.0 for some time now. ever since I upgraded to 2.0, Encore gives me error messages on my project like:
"first play not set" and
"remote control problem".
I don't see how these messages can appear when I'm using a disc image (i.e. a completed project) as the source. does anyone know?

When you click on the Build DVD button in the Disc panel, Encore does a quick check of errors
in the current project. If you have a new, empty project, you will at least get errors about First Play and Title Remote. Those errors have nothing to do with your disc image, they apply to the current project, from which you are trying to burn your disc image.
These errors may be safely ignored, since they don't have any effect on your disc image.
