Now the DVD won't play - 10.4.9

Downloaded the 10.4.9 update today and remembered to include a DVD update of 4.6.1. I had resisted the download, as I always wait until others have done it.
Everything went fine, but when i tried to watch a DVD, nothing happened. The icon is on the desktop, but it will not launch the movie.
Checked the apps and the DVD program is gone. Used spotlight and searched everywhere and nothing.
Tried to download DVD 4.6 and it will not finish. The installer tells me that a newer version of the DVD program is already installed on my boot disk!?
I've searched and searched and nothing exsists of a DVD program on my Cube.
Any thoughts on what to trash so that 4.6 will load?
Thanks.

I get the error message that "a necessary data reference could not be resolved".
This means that you have corrupted or deleted these movies somehow. Restore from your back up.

I clicked "locate" when prompted, now the track won't play at all even from the hard drive though it's listed in iTunes. Can anyone help?

I was prompted to "locate" a track, clicked yes, and now the track won't play no matter where I play it from. I've put it on the desktop, added it to library, tried everything - is there an equivalent "reconnect media" function like in Final Cut Pro? I'd be grateful for any help thanks

Will it play in Quicktime player? If not it may be corrupt and will have to be reloaded from the original source.

On my Mac (vers 10.7.5) I use Disk Utilites to burn a DVD. The DVD won't play on the Mac but will play on my Windows PC and on a DVD player. A DVD created on my PC will play on the Mac. Any ideas why this is happening?

I used iDVD to create an IMG file
You created the video DVD, the IMG file, with iDVD and just burned it with Disk Utility. As Klaus1 pointed out Disk Utility can't create video DVDs.

I just updated and downloaded the new version of iTunes. I then downloaded some music and now the music won't play on my iPod or in my iTunes. The tracks play for a few seconds and then skip to the next track

I just downloaded and updated the newest version of iTunes. After updating I downloaded some new music and synced the iPod. The music doesn't play. It'll play about 30 seconds of the song and then skip automatically to the next song. I restarted the iPod. I restored it. It still didn't work. Then I tried listening to the music from my laptop straight from iTunes...and it's still doing it.
How do I fix it?

I'm assuming the tracks that won't play copy/are displayed with exclamation marks. This happens if the files are no longer where iTunes expects to find them. Possible causes are that you or some third party tool has moved, renamed or deleted the file, or that the drive it lives on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout,or vice-versa, and so is looking in slightly the wrong place.
Select a track with an exclamation mark, use Ctrl-I to get info, then cancel when asked to try to locate the track. Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, or a drive letter has changed, it should be possible to reverse the actions.
Alternatively, as long as you can find a location holding the missing files, then you should be able to use my FindTracks script to reconnect them to iTunes .

Setting series and episode of a TV show in iTunes and now the video won't play

I have an episode of a TV show in my iTunes library that plays just fine on my laptop and Apple TV. The moment I set the TV shows name, series and episode number (so that it is grouped with the rest of the series) the file will not play on laptop or Apple TV.
I'm usually ok on iTunes and all other TV shows I am adding I am able to set the tags without any problems.....it's just this one file.
HELP PLEASE

I'm having the same problem. Windows 7.

Now the vidieos won't play on any of my iPhoto shows or library.

Can you help me. I downloaded picturs and videos into my iPhoto program and made a slide show up. It has mostly stills and some short videos and music. It was running great and I downloaded it to some thumb drives for people on the trip. Other shows ended up downloading too (not sure why) so I deleted the show on the drives. Anyway now when I play the show on my computer none of the videos will play. On the strip I see the picture but when I play the show the screen is black where the videos are until the time has run and then next slide comes up.
Any chance you can help me fix this. None of my videos in iPhoto will play now and I get the error message that "a necessary data reference could not be resolved". I can not seem to find out how to access the data reference???

IDVD problem burning and multiplexing - gets stuck but ejects the DVD and the DVD doesn't play

I am having trouble burning DVDs. Everything seems to be working fine during the iDVD project creation. I can watch the movie and select scenes within iDVD. Then, when I go to burn the DVD, it gets stuck at the burning/multiplexing stage - the wheel just keeps spinning and says there is about a minute left. Yet it ejects the DVD and the DVD won't play when inserted into a DVD player. It will show the intro and the scene selection pages but when you click on one of the scenes, it gets stuck and doesn't play. I have already uninstalled and reinstalled iDVD. The problem persists. It seems like the burner itself is the problem. What can I do to fix it? I have Mac OS X Version 10.6.8 with a 2.8 GHzintel Core 2 Duo and iDVD version 7.0.4.

Hi
Multiplexing error is a very complex problem due to many things (long long list following) - one common but not obvious reason is that material on the iDVD menu goes outside the TV-Safe area (or just touching it).
So first - turn on TV-Safe area and move any object well inside of this.
Wide screen stretched - usually (as I think) it is due to making a 4x3 movie in a 16x9 wide-screen project OR the other way around. This forces one to on flat-screen TV (or other) set the presenting view right - My has 4x3, wide-screen, zoom and auto-wide-screen and I have to switch this by my remote for some DVD I've made "wrong" way.
Now my long long list on Multiplex Error
LONG LONG LONG LIST
Multiplexing Error
PART One.
Use of strange video/audio material e.g. .avi, .wmv, .mp3 etc.
I only use.
Video - StreamingDV (miniDV tape via FireWire) and
Audio - .aiff (as on audio-CDs) (else converted to this .aiff 48KHz)
Photo - .jpg (.bmp known problematic)
Chapters !
A. Using strange letters in video project name e.g. +,/; etc. keep to a-z and 0-9 strange letters in project name e.g. +
as described by Donnyboy69. Does the title of your project have any symbols or decimal points in it. If so, that is why you are getting the error. I had a project that had a + sign which caused the same problem. I renamed it without the symbol and low and behold, it worked.
B. Location of Chapters
• Can’t be at start or end of movie (Skip first/start one - iDVD sets this by it self. At the End - no need)
• Not in a transition (or within 2-3 seconds from it)
Important when from iMovie HD6 or previous - Now also observed when using FCE 4
PART Two.
from Robert Modero.
"Multiplexing Error. Problem during initialization of tracks"
Simply remember to add subtitles to your Quicktime files and menu buttons.
Once I did that, I was back in business.
from Boise Jim
Do a safe reboot (by holding down the shift key until you see the spinning gear on gray background, then release, then restart when your start-up screen appears).
I always makes a DiskImage first and test this so that it runs OK
I use only - Verbatim DVDs
I use only - DVD-R
I burn at an as slow speed possibly e.g. x1
This gives good DVDs
PART Three.
Multiplex Error
Chuck, Chicago 2/7/2009.
Back again. Here is what I have found to work. I also have and use a LaCie DVD-R/RW DL external drive and a LaCie external hard drive as well. Since yesterday I have tried a few ways to burn a themed iDVD project having four 56 minute movies on it, amounting to 226 minutes onto a DVD DL disc, capacity 240 minutes. Apple tech support really didn't know what to do but gave me a very good tip. I had two options left. Apple tech support's tip was to try disc image. One of the replies on a thread with this subject said not to, but my experience today is good. Put your project onto "Burn to disc image," under "iDVD, file." Yesterday encoding took me 23 1/2 hours. Overnight for iDVD disc image, encoding took 21 1/2 hours (again) while I slept. This morning I tried to copy/burn disc image to a DVD with Roxio Toast 7, and it stopped near the end of the burn with some kind of "error" message. So then I tried Utilities> Disc Utility> Burn icon, and followed it through. Be sure to click the DVD DL drive in the window "Burn disc in.". I had one other problem though. At the end of a 46 minute copy, it started to verify, and at the end of verify it rejected the burn. So I tried again, and when "verify" appeared, I clicked on "Skip." The disc finished burning and is doing fine and well. A long and tortuous process, but at last something works. I made several additional copies using Disc Utility. Best wishes. Chuck, Chicago.
2. Disconnect any other external devices not absolutely needed.
e.g. external USB/USB2 hard disks, other FW hard disks etc.
3 Chapter marks in transitions - minimum 2 sec from

(Not a 'guy' but I will answer!)
First, I do not think that mixing wide-screen and standard makes a difference in iDVD.
Second, you should use a better brand of DVD disk. Also, many of us have experienced fewer problems on playback with DVD-R disks. Recommended brands here are Verbatim, Maxell and Taiyo Yuden. Memorex and TDK are not consistent and may not give you a correct burn. They apparently have fewer layers in the composition of the disk. I have always used Verbatim DVD-R disks and have not had any burn problems.
Also, choose a slower burn speed, 4x or less.
Third, to determine if the iDVD project will burn properly, create a disk image file (from within iDVD, go File->Save as Disk Image) and test it. Mount the disk image and then open DVD Player (in Applications) and view your project. If it plays correctly, you can then burn the actual DVD disk from the disk image file using Disk Utility.
From. Boise, Idaho
I did everything I've seen suggested, but a friend (who used to be an Apple Genius) suggested that I do a safe reboot (by holding down the shift key until you see the spinning gear on gray background, then release, then restart when your start-up screen appears).
It worked, and I got a clean burn from iDVD.
Hopefully this can help other people.
by dheb0422
Well, I finally got it, and it was odd enough to post here incase anyone looks this topic up again. Many things were tried, including burning the unedited film, the edited film without titles and chapter markers, abbreviating the chapter markers in case length was the issue (remember the old iMovie used to truncate them when moving to iDVD?). In the process, I noticed that one, and only one, chapter marker was on the same line as the title marker. All the others were on the line above. The only way I seemed able to change that was to clip a few seconds of film. After that last clip, the offending marker took a place on the line above, as were all the others. That run published, compiled completely and burned. That's one for the books.
One user more writes
To add my experience with Multiplex Errors using iDVD (7.0.4), I recently created two iDVD projects
Video from both passed from FCE 4.01 with chapters
One project worked fine in creating disk image file
The other gave Multiplex Errors
I tried suggestions to remove special characters and no chapter marks at beginning, but nothing worked
Note that I've used iDVD for dozens of projects and this is first time I've run into Multiplex Errors
Anyway, for problem project, I tried an experiment where I removed all chapters in FCE and passed to new iDVD project
This time multiplex errors gone
So had something to do with chapters
So now I tried numerous experiments to remove individual chapters and try again creating disk image with new iDVD project
After numerous tries, I was able to narrow problem down to 1 "Bad" chapter mark
That is, when I left the "bad" chapter in my FCE project and passed to iDVD, iDVD gave multiplex error
When I removed "bad" chapter mark (and others in), no multiplex error
As a final experiment, I moved "bad" chapter mark about 5-10 sec's beyond original point and passed to iDVD, the multiplex errors now magically went away and I was able to finally create my disk image.
I have no idea why this worked, but thought I'd mention here in case someone else runs into similar problem.

In addition to Bengt's fine advice, burning errors can occur if you have located any of your menu buttons wholly or partly outside of the safe TV viewing area. Go to your main project menu, then click on View/Show TV Safe Area, to check. Drag into the safe viewing area any buttons that are outside the safe viewing area.
Russ One - suggest this
Multiplex Error-There was an error during muxing preparation
One thing that worked for me was to export the video w/o chapter markers as a self contained movie (thereby not loosing the edits & etc). Then make a new FCE project and import that movie into a new sequence and add the chapter markers. I've used "-", "&" and "," with no problem in the chapter names. Removing the markers or exporting without them did solve the problem but renaming them with just numbers 1,2,3....5, did not solve the problem and since this problem seems to happen with with iMovie as well, it would suggest the problem is in the video or audio and in combination with the chapter markers iDVD just can't handle it. The only other possibility is that both iMovie and FCE share the same or similar chapter marker code that some how is corrupting the markers.
Summary - What to try
1. Chapters
• Only A to Z and 0 to 9 in chapter title
• No Chapter mark at very beginning of movie
• No Chapter mark in or within 2 seconds from any transition in movie
2. TV-safe area for buttons (no one outside this)
3. Safe re-boot
4. No other external devices connected - that are not needed
SDMacuser adds to this
• On #4 ... No ext. devices. Some think this applies mainly to ext. FW. Not the case. Also applies to ext. USB2 as well (not to mention flash drives too).
Do not leave 3rd party devices / camera / camcorder plugged in unless it is being used with iDvd's One Step process. Certain web cams can trigger this also (especially ones with added features like LED light/s that draw additional power from the FW or USB bus).
5. Minimum of 25Gb free space on Start-up hard disk
6. Make a DiskImage first - reduces where problem originates
7. Trash iDVD pref. file
8. Make a new iDVD project
9. Movies in project with same aspect ratio e.g. 4x3 or 16x9
10. No other programs/applications running during iDVD process. e.g. Internet, screen & energy savers

I added some songs to my itunes but now my itunes won't play the songs - it says it can't locate the song although the Itunes match is turned on and it says all of my songs are in the cloud - anyone have any thoughts

Did you delete the hard copy of the songs from your computer after you uploaded them?
If so just highlight the said songs and delete but do not check the box that says delete from iCloud and your songs should play fine.
This happens when the original file is moved from the location that itunes was looking for it at and if you did this because you uploaded it then it will still be in the cloud you just need itunes to read from cloud and not think it's supposed to be finding the original file

DVD won't play in Macbook

Hi,
I have a dvd I purchased from my yoga instructor (so produced professionally (but not that professionally). When I insert the disc into my mac, it whirrs and I get the following error:
There was an initialization error
There was an error reading from disc. IT might be scratched or dirty. [-36]
And that's it. The disc won't play in my dvd player on my tv, but that's not unusual as it's a cheap replacement that doesn't play everything. It does play immediately on my work pc. I know they're video TS files, which I understand can have trouble playing on a mac, but that I can't even read anything on the disc is weird (and my work computer is beyond a mess right now, and it just plays the disc like it's nothing)
Any help would be greatly appreciated, I really want to be able to do my yoga on the road.
Thanks!

Many File Types dragged to iDVD, burned to DVD, won't play on DVD player

I have made a recording on Camtasia (video, pictures and audio). My goal is to make it into a DVD that plays on standard players. Any format I have saved the file to is not working.
Here's what I have done so far:
From Camtasia I have selected Advanced Export and saved it as a MPEG4. Then learned that MPEG are not recognized by many DVD players.
Then I did an Advanced Export and saved the file as Quick Time. Moved it into iDVD, burned the disk and again the disk won't play on either of my DVD players.
I have done another Advance Export and saved the file as an AVI but now only the first 3 minutes of a 30 minute video are being captured.
I know everyone can appreciate that each of these burn processes take a lot of time. I am doing them only to be disappointed (aggravated) that they won't playing on my DVD players (I have tried two). I am using Verbatim DVD +R.
If someone uses Camtasia and iDVD that would be ideal. But at this point, I'd also be willing to try another program just to get the job done.

Hi Vicadea
Welcome to apple discussions. I've never tried Camtasia for Mac. Apparently it's not working very well for you even when you export as a QuickTime movie. I don't know what to say other than it seems like fairly pricey screen capture software ($299) just to have it not work as you expected on multiple attempts.
For much less money and much more reliable results I'd recommend the following for screen capture instead:

My songs are duplicated i itunes but if i remove one entry, the other won't play anymore...what do i do?

After my friend transferred my songs to my new laptop, i have installed itunes. First i had 2 or 3 entries of the same song, because i had a music files (mostly
mp3), and the 2 entries were from Itunes music files. One entry played, the other wouldn't (exclamation point). As i have a couple thousand songs, i decided to consolidate into Itunes Media, thinking i could then uninstall Itunes, Reinstall it and delete my Itunes music folder.
But it probably was the wrong way to go. Now I have an Itunes media folder and an Itunes music folder. If i delete one of them from my computer, itunes says it cannot find the track. But the problem is now it takes twice as much space on my computer and last but not least, almost every song is duplicated in Itunes.
If I delete one of the two entries, the song won't play (exclamation point again). it's like each file of the song exist in his own file, but cannot play if the other version of the song isn't there.
So i'm stuck with a duplicated list of songs in Itunes and 30 Go of songs on my laptop...<
any help would be greatly appreciated!
thanks!

I would guess that if they both point to the same file and you delete one of them, you have deleted the file. Therefore it is no longer there to be played.
I'm not really sure how you got into this situation. I'm also not sure if you have multiple copies of the same songs on your drive or just multiple entries in the library. It sounds like you haven't gotten very far, that you have not yet set up playlists that you would be heartbroken to lose. If you have room on your drive, I might suggest closing iTunes, renaming both of those media folders, then restarting iTunes and creating a brand new library. I would set iTunes to copy media files to the library when it imports them so that it all gets consolidated. I would add the music folder (which is probably a sub-folder of those other folders) from one of your two existing folders and see what happens. Then I'd add the other.
As a normal precaution, I highly recommend backing up your two music folders before starting this.
When all is done and you are happy, you should be able to delete the older folders. This is the step that begs for a backup. First, though, I'd change the names of the two older folders again and see if iTunes plays your music. If not, it didn't make a copy and it's still looking in the old folders. You might want keep them around for a while and only delete them when you need drive space. I am loathe to delete anything unnecessarily, just in case there is a problem.
I'm not a Windows user so I can't help with the details on how to do this on a PC.

IMac 2008 OS10.9.1 external dvd won't play movie DVD's

iMac 2008 OS10.9.1 external dvd won't play movie DVD's. Other DVD/CD's are recognized.
My internal DVD/CD p-layer/burner stopped working 3 years ago like many other iMacs did.
Any help would be greatly appreciated. This is all red because I am ******!

I have discovered, no thanks to Samsung techs, what the problem is, and it might be revealing for others, as well. It seems that DVD Player, which is the app Apple provides in OS x for (naturally) playing videos, doesn't work with external drives if the computer has an internal drive – even when, as in my case, the internal drive is dead.
I have learned, however, of the existence of a couple of alternative, free applications that run video and audio disks with external optical drives, and one of them, at least (VLC), seems to be widely acclaimed. Does anyone know whether bypassing DVD Player could be a bad idea? There were some gripes from one or two reviewers about awkwardness with playing audio DVDs with iTunes, but I'm not sure what they meant when they said that you have to click on individual items in a selection. Would that mean, for example, having to click on each movement of a Mozart trio? That I couldn't play an entire album's contents of another kind of music without clicking on each song?
Getting the internal optical drive replaced would be prohibitive, even if the parts could be obtained, so I guess I'm stuck trying to deal with the external drive I have and finding the best replacement for DVD Player that I can find. The interesting thing is that the drive works beautifully with a MacBook Air I tried it with, so I guess that is because the Air doesn't have an internal drive?
Wouldn't you think that Samsung techs would know all this? The one I spoke to told me to make sure that my system preference for CDs and DVDs was set to open automatically with DVD Player and sent me all kinds of FAQs, plus a way to get an RMA number for a return. Not a word about difficulties with Macs having an existing internal drive. And all after spending a very long time talking with me about what was going on, what the error message was, and so on. I guess the message hasn't gotten to them.
I hope this information will be helpful to someone.

Short content DVD won't play

I've had this problem for years, and I've finally decided to ask. Every time I make a short content DVD with under about 10 minutes of content, my finished Encore DVD won't play in some players. The amount of data written by Encore is visibly small on the disc. I've noticed however, that if I take the same content, and master it in Nero rather than Encore, the content on the disc (burn area) is much larger and it plays just fine on every player. Is there anything within Encore that I can change to eliminate this problem?
Thanks for any thoughts.

"Probably" the reason nero doesn't have the problem is the same as for ImgBurn: it automatically pads the total size. I never remember to pad tiny disks anymore, because I have become dependent on the autopad!
Edit: I see John's second past! That's the other imgburn advantage here: let it figure out the addition!

Now the DVD won't play - 10.4.9
