Multiplexer error - error during formatting

Hi gang
This is an ongoing saga the last couple of days. This morning (using a new user account due to previous problems) set up an iDVD 08 project which is 4.25 gigs in size. If I burn it in high quality or prof. quality the size of the file drops to 2.5 gigs which would indicate a serious drop in quality(?). So set it up to burn on a dual layer DVD (my computer supports this) and it takes right through the encoding and mulitplexing and when mulitplexing is finished it kicks out the message above. I have repaired permissions, removed idvdplist on this user account also. Checked the fcp project to ensure no chapter markers on any dissolves etc. So I am stumped. My next course of action would be to move the files over to my new imac and set up the project on that computer with idvd 08.

I am aware of your efforts to get this resolved. Have you tried a reinstall of iDVD? For the particulars on how to do this, read this thread. http://discussions.apple.com/thread.jspa?messageID=8320683&#8320683
I hope this helps.

I'm trying to burn an iMovie in iDVD and at the end of the whole burn process it says "Multiplexer Error" "there was an error during formatting". How do I fix it so that it'll burn?

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

Simply remember to add subtitles to your Quicktime files and menu buttons.

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

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).

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.
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

Error during formatting

I edited my project with final cut pro, when I try to burn a DVD i get the message
"Multiplexer Error there was an error during formatting" when I use iDVD
when I try using toast 8 I get the same problem. Can somebody tell me where do I start
trying to solve this problem. Thanks

Not sure what type of burner you have but it may be the media you're using. Try using a DVD-R and a 4x or less

Multiplexer error - There was an error during formatting

Hello,
I'm using a brand new iMac 3.06Ghz and iDVD '08. The system software is completely fresh will all relevant updates applied. When burning to physical DVD's or to disk images, I'm frequently getting the following error message:
http://skitch.com/willwood/qysy/idvd
This error message occurs right at the end of the burn process and is occurring with about 80% of the burns I'm doing. Sometimes if I format a disk and try again it works second time round.
I went to an Apple store yesterday and spoke to a genius about this problem. I was told that instead of burning directly to a DVD, I should do the process in two stages. Firstly, get iDVD to make a disk image on my desktop and then use Disk Utility to physically burn the disk image to a blank DVD. Well, I've tried this as well and I'm no further forward. The same error message is being displayed. I've run through this guide: http://support.apple.com/kb/HT1583?viewlocale=enUS&locale=enGB
and in answer to the questions:
1) Software update run, no updates available
2) I have over 820GB of free space
3) There are no non-Apple QuickTime plugins installed
4) No third-party iDVD theme's used
5) I'm able to burn from other applications like Finder and iPhoto
6) Have run hardware test. No problems identified
7) Issue occurs in the final few minutes of burn, no thumbnail shown
8) ?
9) Have tried re-encoding project
10) Intermittent fault - happens on other projects at random
I've done some googling and can't turn up any other information. Also searched these forums but quite a bit of what I've found relates to Final Cut. What else can I try?

I'm also on the trail of a solution. Actually two possible solutions.
I have two iMacs. My older one has OSX 10.4.11 (Tiger) and the newer one has OSX 10.5.3 (Leopard) on it. I was having very similar problems on both machines EXCEPT the older machine wouldn't say what the error was ... it would just say "there was an encoding error" .... but it was happening at the exact same time as the 'Multiplexer Error' so I think it may be the same thing.
Anyway, on the old (Tiger) Mac I tried removing all third party Quicktime components from /Library/Quicktime (such as Flip4Mac, Divx, and Perian) and tried re-encoding a 1 hour 30 minute piece of video. IT WORKED! So now I am in the process of adding those components back in one at a time to find out which one is the culprit. (personally I suspect it might be Perian sin it is the newest one I've added, and I've added it to the old computer and the new computer before this problem cropped up - but my experiments should tell me for sure)
On the new computer (Leopard) I looked at iDVD '08 closer and found that there are three compression modes (in the Project/Project Info menu) - "Best Performance", which lets you encode an hour or less of video - "High Quality" lets you encode more than an hour of video - and "Professional Quality" that also lets you encode more than an hour of video.
Obviously "Best Performance" works (that's the one I've been stuck with for the last couple weeks), but the "High Quality" mode is the one that chokes with the "Multiplexer Error" - But here's the kicker - just for grins I tried using "Professional Quality" mode and I was able to successfully create a DVD with 1 hour and 45 minutes of video !!!
So for now it's looking like a toss-up between Quicktime components being the culprit or a bug in the "High Quality" encode mode. But at least using the "Professional Quality" encode mode lets me create DVDs with more than an hour of video.
I will continue my experiments and let you know what happens.
By the way, the new computer is using iDVD '08 (version 7.02), while the old computer is using the older version of iDVD (version 6.04). So it's version 7.02 that throws out the "Multiplexer Error" in "High Quality" mode (but works in "Professional Quality" mode), and version 6.04 is choking Quicktime add-on components.
I hope this helps you. It sure makes me feel better having a way to encode more than an hour of video.

IDVD message, 'Error during formating'

After adding ILIFE'09
I have successfully burned a DVD using Quicktime media , WMV converted to Quicktime and MP4 converted to Quicktime with my IDVD program, however after 4 days of burning, I suddenly received an ERROR message, after the "time remaining" message stated that the program was not burning, but in fact was "writing the Lead- out". The computer spit out my DVD disk and an air message said, " Error problem during the formating".
So I tested DVD media: DVD-R, DVD+R , DVD-RW
I downloaded MPEG Streamclip 1.9.2 to convert my media to DV. files
I checked my Utilities Disk Permissions and choose to archive and install, to get fresh start.
However after all that work, I am still receiving an air message, "Error during the Formating" when I attempt to burn a DVD in IDVD .
So after hundreds of hours trying to solve this issue I am stumped.
I pimped out my computer last year with all the extra memory doo-dads
...however I didn't change my optical disc drive.
Did I burn out my Optical disc drive?

Well, I was right. I burned out the old Optical Drive.
So I went out, purchased a new drive , installed it myself ...then test burned all the different types of raw DVD disks I purchased ...and I'm happy to report they all burned perfectly.
It would have been helpful to have gotten some type of warning from the computer that the optical drive had faltered. This important information would have given me some type of clue as to what the precise issue was and how to proceed.
This is the information age ...hello?

IDVD "error during formatting"

ok so this is my first movie...and I must say I had to figure a lot of things by myself...dispite all of the help from others and what seemed to work for others on forums, discusions, so on and so forth...it didn't help for me...so I ussually have to figure these things out on my own...but I thought I would give it a try in asking anyway.
PLEASE MAKE YOUR ANSWER UNDERSTANDABLE NOT LONG AND IF POSSIBLE GIVE INSTRUCTIONS!!! (thank u X3)
If you are still reading this then thank you :3 lol
ok firstly
(1) there is no problem with how many videos and how much music I have on the menu(s), trust me...I know
(2) I have much content...(don't make me count)...I have a movie and extras...but like I said that shouldn't be a problem
(3) I have made a dvd before and it worked fine!
Short Summery (and by short I mean moderately not too long)
At first my movie contained too many sub-menus in my extras (too many being 4) (most people said the problem was because of too much video in the sub-menu...well...they were wrong) so I reduced it down to 3 and it seemed fine, but then I ran into another problem...there was just too much content...so I when to project> project info> and changed it to high quality.
I later wondered, if I put it on "profesional quality" would it allow me to have all 4 of my original sub-menus? I ended up putting my dvd in, and checked to see what the quality looked like (which it looked nothing like how it looked on my computer!! POOR QUALITY!!....or I could just be saying that because I'm a perfectionist and things like that bother me....ok....to the normal human eye the quality was fine)
I wanted to change a few things, so I decided "what the 'hey'" and changed it to professional quality and it was fine, there was no error or anything, so I left it like that.
I fixed the movie up, checked for errors (there were none) and started to burn my DVD (which btw took a whole 5hrs!!!) and in the end it stopped and said "error durring formatting" I mean....WHY DIDN'T YOU TELL ME THIS BEFORE YOU RUINED MY DVD??!! AND DID IT HAVE TO TAKE 5HRS FOR YOU TO REALIZE THIS??!!?!?!?!?!? and it only told me there was an error....would you like to tell me WHY????
What I believe the problem might be
possibly I'm thinking it might have to do with either
(a) profesional quality does not change the fact there are too many sub-menus and idvd is just too dumb to tell me this ahead of time
(b) I forget at the moment .... but you get the idea
PLEASE TELL ME YOUR THOUGHTS
I'm extremely angry because I had to take 2 sub menus, then change them back, and then wait 5 hrs to be told there was an error in the very ending of the making of my movie!! (not to mention some other problems I had...but I'll leave them out) I wanted to get this done soon, and apparently that's not going to happen HELP ME!!!!!

WHY DIDN'T YOU TELL ME THIS BEFORE YOU RUINED MY DVD??!! AND DID IT HAVE TO TAKE 5HRS FOR YOU TO REALIZE THIS??!!?!?!?!?!?
You can always check the capacity meter / project info in iDvd. Green means you're good to go whereas red indicates you'll likely have issues when it comes to dvd quality and/ or encoding. Assuming it does show green, then burn a disc image from the file menu in iDvd and test playback with apple's dvd player app prior to burning. Far fewer coasters this way.

Multiplexer error during Save as Disk Image

I'm having this problem occasionally. In this particular case, it has happened twice. The second time the DVD was partially encoded so it did not take so long to fail. The first time it failed after over 12 hours of encoding.
My question is ... I am really pushing the limit on the size of the movie. It is 239:18 minutes. I get no warnings about this being too long. It says it is using 7.6 GB out of 7.7 GB. But could this be an issue?
Does anyone have experience of problems with the size of a DVD file?

I've got close to 4 hours on a DVD before ... maybe
slightly less than this one but not by much. (If I go
over the 4 hour mark then I'll get an error in iDVD
and won't be able to start to save an image file.)
The problem is, iDVD really doesn't know EXACTLY how large the mpg-2 encoded video and multiplexed audio file will be until does it. You may be in that 'gray' region where it thinks your content will probably fit but it won't.

IDVD09 Multiplexing Error formating disk, when saving to a disk image

I am able to burn a disk but when I to to save a disk image, after four hours of churn, when it goes to write the image, I get " Multiplexing error in formating disk" and iDVD quits. This is a real pain and very time consuming and happens every time I try to save a disk image from the project. Any ideas on how to get around this would be appreciated.

I am up to latest software 10.5.6/ I am saving disk image to internal 450 GB drive. I found that I was suprisingly low on empty space (14GB) that might have been my problem. I recently uloaded a buch of video (like almost 3 hours, did not realize how close I was to being ful!I will post here tomorrow after I go the 5 hours again to make another pass at the Disk image!

IDVD multiplexing error or freezes

I am trying to burn 2 videos onto a DVD but I get an error code or else it just hangs and will not complete the burn. I imported the videos into iphoto and then clicked on SHARE and Send to iDVD. I used a theme and put in the picture in the drop area and then clicked on Burn. This has worked before. Then it appeared to be saving everything so I left it overnight to finish the burn.
It came up with a multiplexing error. The error said to check the encoding settings. It was already set on Best Performance and this has worked before, so I did not change it. The first video is just under 30 minutes and the second video is about 8 minutes long.
The second time that I tried to burn to iDVD it acted fine and said it was Done with multiplexing but said there was about 38 minutes remaining. It just hung or froze. I had to cancel it and again have no DVD. I am using iDVD version 7.1.2 and am using Snow Leopard v. 10.6.8 on a MacBook Pro with 5 GB of memory. How can I get iDVD to burn these videos? I am using Memorex DVD+R and have burned videos to a DVD successfully in the past. Thanks.

First follow this workflow to help ensure the best quality final product:
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 and launch DVD Player and play it. If it plays OK with DVD Player the encoding was 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.
That being said read Bengt Wärleby's post in this topic: HT1645 I was burning a DVD and the following message showed up. multiplex error There was an error during formatting. What is a multiplex error and what do I need to do about it? It's the most comprehensive teatise on the subject that's been posted in the iDVD forum.

Multiplexer error message when trying to burn DVD in iDVD

When I try to burn a DVD in iDVD, at the end of the burning process, I get a message that reads "Multiplexer Error" "There was an error during formatting".
Can anyone out there give me advice on how to remedy this?
Thanks!

When iDVD isn't functioning correctly, a basic maintenance procedure to try is:
1) Closing iDVD and trashing the file com.apple.iDVD.plist found in User/Library/Preferences.
2) Doing a permissions repair using the Disk Utilities app on your Mac.
Instead of burning directly from iDVD, try saving as a disk image (an option in the iDVD File menu). This will take a while as the encoding is redone. If you get a successful disk image, open it in your DVD Player app to check it out. If all O.K. burn it at a burn speed of 4x or less with Disk Utility to a DVD-R disk of good quality, like Verbatim or HP. On my computer, Disk Utility defaults to 4x burn speed, which is good.
See if any of the above helps.

Problem burning dvd "multiplexer error"

Hi there, I am trying to burn a dvd using iDVD. Apologies for what may be a simple question but I am very new to Macs after a live with the evil PC!
All appears to start off well, the total project is about 6Gb, and I am using a double layer DVD+R. I have gone into the project settings and amended them to ensure that it is set and recognised as a dual layer disc.
All starts off well and the "Creating your DVD" screen runs down through "prepare", "process menus", "process slideshows", and "process movies"
It then starts the "Burn" section and the progress bar moves across whilst it says "muliplexing". It gets right to the end of this and then the following error comes up "Multiplexer Error - there was an error during formatting".
Any ideas or suggestions gratefully welcomed!
Thanks

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 trys, 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 mulitplex error
As a final experiment, I moved "bad" chapter mark about 5-10 secs 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.

Multiplexer 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.

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.

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.

IDVD is giving an error during multiplexing or it will force close while burning. Please help!

I've been using iDVD to burn videos for awhile now. This time around it is either force closing while burning or near the end it gives a error while multiplexing and will not continue. Is there something I can do to fix this? Or another program I can use to burn the videos to DVD.

Read Bengt Wärleby's post in this topic for possible causes: Multiplexing Error: Apple Support Communities.
Also 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.

Errors during multiplexing?

I have not been able to burn imovie project through idvd.
What is multiplexing error... anyone?
Thanks!

Karsten is absolutely right. this is a problem that has come up many times before-in the iDVD forum.
Quit iDVD.
Locate a file named com.apple.iDVD.plist and get rid of it. iDVD will create a new one the next time it runs. Empty the trash and run a permission repair using the Disk Utility.
The files to trash are found here:
-->/Users/YourName**/Library/Preferences/com.apple.iDVD.plist
You didn't rename, move, or delete the Movies folder found in your home directory, did you?
Also, you aren't using Norton Anti-Virus-right?
What was the source of your audio?
Oh-and one more thing-read this from Apple (in case you have never opened iDVD before):
iDVD: Slideshow error while rendering or encoding

Multiplexer Error Please help!!!!!

I am trying to create a dual Layer DVD in iDVD which on two occasions has given me a Multiplexer error. This error tells me that it has happened during the formatting stage, the result of which, has rendered two Dual layer disks unusable.
What is the likely cause of this?
I would appreciate any help so that I do not waste any more Blank dual layer disks as they are not cheap and I can't find any dual layer re-writeables to purchase anywhere.

Assuming you have the available HD space to do this, why not just make a disc image from the file menu in iDvd? Then use the advanced menu to lower the burn speed to 4x or lower prior to burning to Verbatim / Maxell DVD-R
I'd highly recommend using apple's dvd player app to test the above image prior to burning. That way you'll hopefully save on making any additional coasters with DL media.
Which encoding setting are you currently using?
