DVD is ejected during multiplexing

My iDVD ejects the dvd in the mutliplexing stage of burning. The DVD has nothing on it, so I can use it for other things, but I cannot seem to get my movies burned to DVD. Any suggestions?

Check Bengt Wärleby's post here for possible reasons for the problem: Multiplexing Error: Apple Support Communities..
Follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

Dvd keeps ejecting during multiplexing and burning in idvd

Ok, I realize a lot of other people have had this problem and somehow managed to resolve it. I have done a lot of reading and experimenting but so far NOTHING has worked. So, to recount everything that I have tried and all the details to this problem:
First of all, I would like to mention that I have successfully burned a number of DVDs in idvd in the past. Then suddenly it just stopped working.
I have run a verify/ repair disk permissions. I have deleted all the idvd files off my computer, the .plist and preferences file, restarted, and reinstalled iDVD TWICE with a custom install. I have 500 gb of free space on my boot drive. I used a cleaning disc on my SuperDrive, and my regular DVD player. I switched to a better brand of blank dvd. I am now using Sony DVD-r, 4.7 gb discs although memorex DVD+r always worked just fine before. The project I am burning fits on the disc. I am not using chapters. I tried turning on the tv safe area and made sure everything was inside it, but still the same problem. I tried booting up in safe-mode then restarting. Still, same issue. I am burning at 2x speed, using professional quality setting. The project preview works just fine. It goes through the whole idvd process just fine, until the burning and multiplexing. After burning about 10 minutes of the project, the disc ejects suddenly. Idvd says "done" but then at the bottom it says "about one minute left" and the little burning wheel symbol is still spinning. The disc plays fine in my DVD player till about ten minutes in, then freezes and eventually goes back to the main menu. I can see on the disc that it is only partially burned.
Oh, and I have also tried saving to a disc image and burning with toast and disc utility. Once, this actually did work with toast and resulted in a playable DVD. The weird part was that I still got the error sense key message in toast and thought I had made another coaster, but when I tested the DVD it worked fine in my regular dvd player only (it was not readable in my xbox or ps2). Since that one fluke, however, it hasn't been successful. Disk utility did not work for burning the disc image. I am absolutely at a loss here...somebody PLEASE help.

I believe I have finally fixed the problem but I am going to post what I went through just in case someone else ever runs into these same issues, maybe I can save them some time. I went through so much troubleshooting and each problem solved seemed to result in new problems, so, let me recap.
First, computer was working fine. Burned a DVD, it worked. Then a few days later, tried to burn another DVD. It didn't work. I tried different brands of discs, different types of discs, (-r and +r) sometimes there was a partial burn, sometimes no luck at all and an unusable, unplayable disc. The disc would eject early during the burning phase, giving me simultaneous contradictory messages that it was both "done" and had " about one minute left".
I tried running a verify/ repair disk permissions. Everything came out fine, but still no burned DVDs. I tried uninstalling and reinstalling idvd. I tried a cleaning disc. Still no go. Sometimes idvd would crash or freeze on me or give me error messages. Result varied depending on what i tried, but were never good.
Then I bought an external drive and tried saving my DVD project as a disc image and burning with toast as many people have suggested. This worked! So, I concluded that my SuperDrive was faulty but I'm not going to bother getting it replaced right now because the external works just fine. I thought my problem was finally solved, but then...
I noticed that upon restarting, my computer would display a white-gray screen as is normal, with the familiar apple symbol, but now a new addition: a very annoying loading bar that took 5-10 minutes to load. Unacceptable!!! Also, I noticed shortly after that iTunes did not work. It wouldn't even open, but crashed due to an error and asked if it could send a report. I tried deleting and uninstalling iTunes but that didn't work.
I ran another verify disc permissions with disc utility, and I got a very bad error message. It said there were errors on the drive and it could not be repaired and it said I needed to start up from the Mac OS X install disc and use disc utility to repair the volume. Problem with that...my install disc says it can't install on this computer. I soon learned from one (finally) helpful apple support guy that the reason for this was that I am running snow leopard 10.6.8 and the disc that came with my computer was for 10.5.2 or something.
On a side note: I had called apple support before and specifically asked if the reason the disc didn't work was because it was for a different version and the guy said he had no idea if that was the reason or not. Jerk. CLEARLY, that was the reason and my ignorant butt didn't know any better and he wanted me to pay 19.99 just to answer that question for me.
So, I went to the apple store and purchased snow leopard. It was delivered today, I started my computer from the new snow leopard disc and repaired my drive. Restarted. A bit slow restarting but no more loading bar and not as bad as before...iTunes still didn't work but I completely uninstalled a reinstalled it again and this time it seems to be working fine. Idvd is working, I saved another movie to disc might. And am assuming it will still burn fine with toast in the external drive.
During my arduous troubleshooting I discovered that I most probably have the seagate 1 tb hard drive that was recalled by apple due to its tendency to fail...whether this has been the root of my computer's troubles from the start, I still don't know for sure. But, everything seems to be functioning correctly now at least and since my computer has lasted this long without hard drive failures, maybe it will be ok. It's possible that I somehow caused the errors while I was fiddling around on the computer trying to fix idvd and iTunes. Hope this is helpful to somebody, someday. I did gain a lot of advice from various forums on the web and found many people having one or more of the issues I was running into, so I thought I should record my process here for others as well.

IDVD ejects during multiplexing and burning

Hi folks,
I've used iDVD previously (several times) to create DVDs of movies I've created in FCE4. Today, the program goes so far, then ejects the disk during the "multiplexing and burning" / "writing lead-in" portion. When I check, there's nothing on the disk. Anyone every experience this? And, if you know, please advise as to how I might fix the problem.
Thanks very much for your expertise.

Multiplexing Error
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

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

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.

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.

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.

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.

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

Burning ejects during "multiplexing and burning"

When I burn a dvd it goes the whole way and then with 10 minutes left when it is doing the "multiplexing and burning" part, it ejects before finished and I get a blank DVD. Tried a 1000 times. Has anyone else experienced this?
I've burned dvds before and had no problem.

IDVD ejects disk during multiplexing and burning

Having burnt many DVDs previously, I have suddenly started struggling.
Having edited in FCE HD v3.5.1, I export to Quicktime and then build the dvd as normal in iDVD.
The project has no errors and then I burn it using Verbatim 16x certified 4.7GB/120 min Advanced AZO+ DVD-R disks.
During Multiplexing and burning (with between 1 and 3 mins left, it ejects the disk saying saying done but nothing is burnt.
To try to remedy this, I have set the burn speed to both 2x and 1x. I have also turned the computer off, removed all cables and battery, held down the power button for 10secs then rebuilt and retried. Still nothing.
I saved a disk image but I don't know how to then make that into a burnt dvd. Any advice on that would be appreciated but moreover, I'm sure I shouldn't have to jump through so many hoops to burn a dvd - Mac's should just work shouldn't they.....?!

Here's even more of an update, with no joy....
to refresh, I have a macbook pro 15" - the older one with the silver keys.
I make 3 min movies in FCE then export using quick time conversion and try to burn with iDVD.
The problem: I can burn data CDs but i can't burn a DVD anymore. This seemed to start after the update to 10.5.7. At that point I tried to fix it with no joy so due to deadlines, used another machine! Now a few months later, i come back to it and still no joy.
I have reset the PRAM
I have reset the CMR
I have upgraded to Snow Leopard
I have sprayed compressed air into the drive
I have reduced the burn speed to 1x
But still I can't burn a dvd. When iDVD goes through the stages, everything is OK until it gets to multiplexing and burning, it says it is 'writing lead in' and has 1 min left (or 2 mins when burning at 1x). Then the blue status line suddenly goes all along and the machine spits the dvd out saying done. (although iDVD does not revert to beginning of the process, it kind of freezes).
idvd version 7.04 if I hadn't said before.
Please help, I'm despairing....

HT1645 whether i use a DL DVD or just a DVD R, it tells me there was an error during multiplexing. I have tried changing every setting, best performance, professional quality, etc. and still get the same error message every time i try to burn to dvd.

whether i use a DL DVD or just a DVD R, it tells me there was an error during multiplexing. I have tried changing every setting, best performance, professional quality, etc. and still get the same error message every time i try to burn to dvd.

Welcome to the forums.
Looks like that error message does refer to encoding (see http://support.apple.com/kb/HT1645) but a problem could be that your video has to be reloaded into iDVD if you started the encoding process and then switched settings. You could start a new iDVD project, or try deleting encoded assets.
Let's start from the beginning -- what length of video are you trying to fit on the DVD? (this will indicate what encoding options you have). Double layer DVDs can be finicky and are used for video more than 2 hrs long.
Use good quality media -- Verbatim is often recommended around here, and I've used Sony DVD-R with good results.
For a detailed treatise, see: https://discussions.apple.com/thread/3926901?tstart=0

Another headache - "problem during multiplexing/burning - buffer underun"

Hello,
After many iDVD issues, I finally got the burning process of my DVD project.. half way through it spit my DVD out and gave me these errors:
"Errors were found during the burning process:
The recording device reported the illegal request: Buffer underrun. (0x21, 0x02.)
There was a problem during multiplexing/burning."
What is this supposed to mean and how can I just burn my DVD?!
Thank you
Chris

It's been awhile since I had this error crop up, but I know 2 things that caused it for me.
1) Bad DVD media. It happened a lot when I was using some cheap, off brand DVD-R's. More expensive Sony DVD's (white) are much better and more consistent. The time wasted with bad burns from bad DVD media is not worth the time.
2) It could even be a problem with your DVD burner going bad, but not as likely. I did have one SuperDrive replaced because I started having problems even with good, recommended brands of DVD media. However, try getting some better media first. Don't buy a lot. Try out a small package of DVD-R's or buy a disc from a friend to try out a brand.
Another possibility: Lack of sufficient, free hard drive space. Here's what iDVD 6's help file states:
"When you burn a DVD, iDVD needs temporary space on your hard disk to store the encoded files for your project. To burn your iDVD project to a single-layer DVD disc, you should have 8-10 gigabytes (GB) of free disk space on your hard disk, depending on the size of your project. For double-layer discs, you need 15-20 GB of free disk space."
Apple's support forum describes "buffer underrun" in more detail at:
http://docs.info.apple.com/article.html?artnum=25750
You might also want to defragment your hard drive (with a 3rd party utiility such as TechTool Pro) so that you don't have a fragmented hard drive when burning a project.
Speed rating of the DVD media- I've seen reports that some SuperDrives work best with media rated the same as it's maximum burn speed (e.g.- 4x, 8x, etc). I would recommend trying to find media that matches your SuperDrive burn speed, or no more than twice the burn speed.
I hope this helps.
You didn't mention which version of iDVD you were using or which operating system. Sometimes other users have tips for you based on that info.

IDVD having problems "during multiplexing/burning"

Help please:
iDVD is not burning DVDs for me.
it goes through the whole process seemingly fine, then at the end shows the error message: "problem during multiplexing/burning".
I have a G4 emac. 800 Mhz 10.3.9
external Lacie dvd burner (that burns fine on wife's imac)
I was having this problem earlier, then erased the hard drive to start clean. Didn't seem to help.
I upgraded the Lacie driver, etc too.
thoughts?

Ah then if Toast has a connection issue and iDVD is having issues when burning, it would appear that your issue is unrelated to iDVD and instead a system or hardware problem. Unfortunately that might be too hard to diagnose here in this forum, at least not with a ton of non-iDVD related back and forth questions and answers.
Did you play the disc image on your computer to see if the titles made it into the disk image? My guess if they didn't make it onto the DVD blank, then they are not in the disk image either, although maybe they were?

DVD tray ejects on reboot. Cannot complete install.

This is a recurring problem. Whenever I reboot my system, the DVD tray ejects, so when SL goes to reboot, it pops the DVD out and just boots up on the old system. I've tried holding down "C" during reboot. I've repaired permissions. I've unplugged all peripherals.
Any more suggestions from the room?

I'm sure you have your reasons for running AV software so I won't give you the standard speech on that topic.
Ha! The only reason is a not-good one: the machine in question is my uni's, and my IT folks insist, however unnecessary (and problematic!) I tell them it is. They're mostly Windows folks, so they're prone to virus-paranoia.
I haven't yet told them that I've upgraded to SL -- I didn't exactly ask for permission -- and I certainly haven't mentioned that I've uninstalled the AV software!

If you don't have a SuperDrive you will not be able to burn DVDs.
Did iDVD come preinstalled on your Mac? If it did then you should have a SuperDrive and be able to burn DVDS. Check the Disk Burning section of System Information
to see what you can read and write with your optical drive:

DVD Drive Ejects on Bootup

I have a PowerBook Pismo (Firewire and bronze keyboard). OS X 10.3.9 with all the latest secutity upgrades.
When the machine starts up, the DVD drive ejects whether or not there is a disk in it.
This makes it difficult to boot from the install CD to run Disk Utility.
Has anyone had this problem? Are ther any know fixes

Sy B,
Disconnect all USB devices including a USB mouse, then restart...see if the drive tray still pops open. Some known troublemakers are Adesso Tru-Form keyboard, Griffin iMate USB/ADB adapter, Keyspan Twin serial, and possibly others.
Test each device individually, then see if updated software is available.

I'm running OS X 10.7.5 on my MacBook Pro. I can't get a DVD to eject. I'm getting an error message "supported disc not available". How can I get the disc to eject?

I'm running OS X 10.7.5 on my MacBook Pro. I can't get a DVD to eject. I'm getting an error message "supported disc not available" when I try to use the DVD player eject button. It also does not show up on my desk top as an icon as it normally would. How can I get the disc to eject?

DVD ROMS Ejecting after start up.

System Configuration:
CPU: 2.5 Ghz P4
Motherboard: Motherboard- MSI 865PE Neo2-V (V Class)
Chipset 865PE + ICH5 Chipset base
RAM: 500 Mb
Video Card: ATI Radeon 9200 SE
Operating System: Windows XP home edition
Nb. Two DVD drives connected master & slave on IDE2
I have an unusual situation. Please help. I have run out of ideas.
Dilemma
1. I boot up my system.
2. I click to enter my desktop environment (3 other users share this PC).
3. My system starts to load my processes.
4. While loading the processes my DVD drive door(s) shoots out in the open position. Sometimes both shoot out together and sometimes only one.
5. If I go into my windows explorer, I notice that the drive letters for the two drives are missing. I then have to reload them by using “my computer” management area. If I do not do this my applications will tell me that no drive exists. I have a DVD ROM and a DVD RW.
Other observations:
The drives never go missing in device manager. The drives only go missing in windows explorer if the DVD doors open. Sometime the doors may stay shut and everything is well. Sometimes the problem is frequent and sometimes it seems to have gone away.
Been there done that:
1.   I unloaded all DVD burner software
2.   I changed the IDE ribbon cable
3.   I unloaded the CD/DVD drivers and rebooted
4.   I disconnected one DVD at a time and rebooted.
5.   I checked for viruses using Norton 2005 (with latest definitions)
6.   I checked my application/disc integrity using Norton Win Doctor
7.    I Joined this forum for help

Update:
10.   I swapped around the cables going to the IDE ports on the motherboard. Switched ROMS to IDE 1 and switched HD to IDE 2
11.   I dismounted the virtual drive in CD Anywhere manager.
Problem disappears after I “only” completely remove cd Anywhere:
I completely removed the cd Anywhere software. Also using cdacleaner.exe and removing the registry entries as instructed by the supplier. The problem did not return.
Stop the clock –solution found.
I have an application called CD Anywhere that starts up at the beginning of loading. Only after I disabled this process that the problem with the DVD drives ejecting was resolved. I contacted the supplier about the problem and they furnished me with a fix, so far so good, everything is working fine. If you are wondering what CD Anywhere is, it’s a virtual drive software for convenient loading of CD images without the hassle of physically loading the original cd. Its supplied by a company called Vcom.

Optical DVD drive ejects any inserted disc and does not work!

I can not read or write certain DVDs in my Mid-2009 MacBook Pro since upgrading to Mountain Lion.
I insert an empty DVD-R (Verbatim) and it is being ejected. I insert a recorded DVD-R (Verbatim) and it is being ejected.
I have tried a commercial Video DVD - (Sony) and that one actually did work ... so I am pretty clueless - I can not write any DVD right now.
In the forum I have found many posts regarding this issue under Lion already.
However, my drive used to work fine under Lion and I was able to watch / record DVDs etc.
Now, it is no longer working and I can not use it. Does anyone know how to solve this?
So far I have found the following hints (which did not work for me):
ALL OF THESE THINGS DID NOT WORK:
1) Reset the PRAM (https://support.apple.com/kb/HT1379)
2) Uninstall all virtual machines (Virtual Box, etc.)
3) SMC Reset (https://support.apple.com/kb/HT3964)
some people talk about it being an issue with the 64 bit kernel and that you should try to reboot into 32bit (holding down 32 on startup)
https://support.apple.com/kb/HT3770
others blame it on the UDF format (https://discussions.apple.com/thread/3413998)
There are too many articles in the forums about this - more to make this a random issue.
The most disturbing thing to me is that multiple of the people in these threads contacted Apple and in the end where told, it's probably a bug... now why is this - obviously critical bug - not being resolved, yet ?

the list could probably be continued, but I'll leave it at this

I also had the same problem shortly after upgrading. My optical DVD drive ejects any disk I put in. This started about 2 months ago.
I just got back from the Apple store, after setting up an appointment, and they told me that my life is horrible because my MacBook Pro is no longer under warranty as of 32 days ago. This is really BS.
However just like any other company that treats me with poor customer service I just take my future business elsewhere and make sure not to recommend them to any friends and family - as well as tell them about my horrid experience.
