I've read a number of discussions about this. I don't have any disc space, file name, TV safe area, strange file type, disc type, chaper markers, etc, etc issue; ALL checked OK. I used iDVD version 7.1.2.


Three files totalling 101 mins converted by Toast to .mov and .mp4 formats had the same error when using iDVD Encoding: High Quality or Professional Quality settings. Error message pointed me to the web version of iDVD help regarding these settings. After many, many hours of testing, my conclusion is that these settings are CRAP. All the while taking at least eight hours before the error! Each of the three settings displayed the progress through Rendering Slides, Encoding Slides, Rendering Audio, to the fateful Multiplexing & Burning.


Proof. Same three .mov files Save to Disc using dual layer (DL) disc setting and Encoding: Best Performance worked fine. Burn to an actual DL disc worked fine. Less than two hours of video on a DL disc!


I can't believe I'm saying this. Don't use iDVD in this situation. Buy Toast. My version is Toast 10 and the same three .mov files were burned onto a single layer DVD in at least a quarter of the time and the quality was only very slightly less than the four times more expensive dual layered disc produced by iDVD.


iDVD Encoding: Best Performance seem to work OK; reduced time. The other two settings are CRAP with error after error after error.

    Just a few simple questions.


    What brand and type of DVD were used ?


    What Audio and Photo file format and Video-codec was on Raw-material (all of it) ?


    Any strange Text font's used ?


    Yours very interested Bengt W

    Hi...same problem. Burned one DVD, turned out fine. Made a few minor changes, but major change was to go from Best Performance to Professional Quality. Once I made this change, I got the same error message over and over, even though I changed back to Best Performance. Map is OK. No chapter markers, no submenus, just wanted a quick burn. I'm using Playo DVD-R, but since one burned just fine, I didn't think the disc brand was the problem.


    So, after wasting a lot of time trying over and over to burn the disc, I saved the project and quit iDVD to see if that would clear the error (duh). If that didn't work, I was going to restart the Mac. But it did work and the disc burned.


    While it works, this may not be the best fix for everyone. My movie is only 38 minutes, and not complicated. All I had to do was insert the photos into the drop zones again. It took more time to keep trying to burn discs without getting the error message than it did for me to start over. If you try this, BE SURE TO SAVE THE PROJECT FIRST!


    I have been using a Mac since 1986—you'd think I'd learn...

    All info that can help tracking this problem down is of value. So



    • Audio and

    • Photo file format and

    • Video-codec was on Raw-material (all of it) ?


    Especially codec for

    • Film 1

    • Film 2

    • Film 3 (as adding this set off the problem)


    As to encoding method - I always use - Pro. Quality - long time since I got Multiplex error - so I doubt the encoding process to be the culprit.


    iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.1) and iDVD 6 has the two last ones


    • Professional Quality

    (movies + menus up to 120 min.) - BEST (but not always for short movies e.g. up to 45 minutes in total)


    • Best Performances

    (movies + menus  less than 60 min.) - High quality on final DVD (Can be best for short movies)


    • High Quality (in iDVD08 or 09) / Best Quality (in iDVD6)

    (movies + menus up to 120 min.) - slightly lower quality than above


    Menu can take 15 minutes or even more - I use a very simple one with no audio or animation like ”Brushed Metal” in old Themes.


    About double on DL DVDs.


    Yes I use Roxio Toast™ too - especially for back-convert old DVDs and when needing to squees in more onto a DVD as iDVD can do.


    Yours Bengt W

    1. I never worked for any computer business - ever.


    2. .mov is no codec - it is a container and can hold a variety of codecs - some working in iDVD others do not.


    3. Your tone don't inspire me to cont. this tread.
