Won't Burn. Error While Multiplexing. I've tried everything. Please help.

Question

I've seen this topic all over the boards. I have iDVD6 and my project won't burn because, after a couple of hours of asset encoding et. al., I get a message saying that there were errors while multiplexing. Here's what it's not:
1) It's not that I have chapter markers in bad places. I followed the rules. Then I eliminated all the chapter markers.
2) It's not that the sound is Mpeg. It's properly formatted.
3) It's not too long. I get the same problem with a 60 second version of the movie. And I have plenty of space on my hard drive.
Here's what I thought it was:
1) The film was created with three cameras, at least one of which was using 12 bit sound and set on LP, two problems I've learned that iDVD doesn't like. However, to solve this problem I did the following:
a) I created a full quality Quicktime Movie
b) I imported that full quality Quicktime Movie into a new iMovie project.
c) I exported the movie back onto my video camera, with the camera set for 16 bit sound, and LP.
d) I opened a new iMovie project and imported the new, edited, film back onto my computer.
e) But when I tried importing it into iDVD6 I got the exact same message about the multiplexing error.
It doesn't seem possible that I cannot use iDVD to burn my project. Any thoughts?
(I don't have toast, and I don't know any other editing programs. I want to use iDVD and iMovie. That's what I paid for and they should work. I assume that since this problem is all over the Forum boards that there may be a bug in the program. Has anyone heard about a patch?)
Thank you to all who resond. Much appreciated.

Answer 1

Charlie,
Tell us about the computer you're using. See my specs below for guidance.
As John said, make a disk image and then burn the DVD.
Suggest you create a disc image and then burn the DVD. File/Save As Disc Image...
http://docs.info.apple.com/article.html?artnum=164927
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.)

2) It's not that the sound is Mpeg. It's properly formatted.
What does "properly formatted" mean?
at least one of which was using 12 bit sound and set on LP, two problems I've learned that iDVD doesn't like.
As you've learned, that makes iDVD VERY unhappy.
e) But when I tried importing it into iDVD6 I got the exact same message about the multiplexing error.
You got the multiplexing error when importing into iDVD??? Or do you mean when encoding/burning direct to a DVD-R (not DVD+R or any other format)?
