iDVD: Files exported from iMovie 11, one works, one "Unsupported File Type : Unknown
I used footage from the same camera (taken on the same weekend using the same settings) in several different iMovie "projects". All were shared from iMovie 11 as "File" using the quality setting "SD 480p".

In Quicktime Player, all ".mp4" files will play and they show the following info in its inspector:
Format: H.264, 854 x 480
AAC, 48000 Hz, Stereo (L R)
FPS: 29.97

One exported file will drag, drop, and burn in iDVD just fine. The other two files show the error "Unsupported File Type : Unknown format" as soon as I try and drag them into iDVD.

The only difference I can find is that the one file that works is about 803MB, while the files that don't work are 1.87GB and 3.98GB.

All files and the iDVD project are in the same folder on my startup volume. I've tried deleting but that didn't help. I've tried rebooting and starting the iDVD project from scratch but I get the same results.

Mac OS 10.9.1
iMovie 10.0.1
iDVD 7.1.2

Any ideas?

How long are those movie clips? iDVD cannot make DVDs longer than 120 minutes, .mp4 is probably H.264, and 2 and 4 gigs in SD H.264 will be more than that.

The clips are 20 minutes, 49 minutes, and 103 minutes. Adding them in any order gets the same results. I re-exported one of the non-working files and got the same result again.

It does sound like size or duration is the problem with the non-working files.

You might break up the two problem files into several parts (I'd aim for the running time of the one file that worked) and see if the parts will export individually. I'm thinking that certain output formats produce larger output files for a given length of running time, but with the H.264 codec that shouldn't be the issue.

I took one of the large clips that didn't work before and cut it down to about 11 minutes/440MB. iDVD gave me the same error when trying to add it.

As I mentioned in my previous posts, I'm using iMovie 10.0.1 which has very limited quality adjustments. In every case I chose the smallest size, which iMovie 10.0.1 calls "SD 480p (854 x 480)". I used this same setting on all exports.

I still have iMovie HD (6.0.4) and iMovie '11 (9.0.9) on my iMac so I tried both of them. In both cases, they could import only the file that works in iDVD. Both older versions of iMovie choked on the longer movies exported from iMovie 10.0.1.

I have many many hours into the editing of these clips and I do not want to have to go back and redo everything in an older version of iMovie. Might I be better off going with a different DVD creation software? Or am I out of luck? Because I can't really change iMovie 10.0.1's export settings, I'm afraid there's nothing I can do to get it to export it as something that iDVD can use (really, I can't even tell why it's different and why iDVD doesn't like it).

Sounds like the problem is with iDVD, yes. Maybe you should give something else a try. If it's just about burning the DVD and not adding menus etc, something like ffmpegx can do it.

It's a wedding DVD for some friends and I was really counting on some nice looking menus. The last time I did this I was using iMovie HD which gave me the ability to use chapter markers that would work straight in iDVD and the end result was great. It's really too bad that Apple has let this integration slip so much, I really liked when "it just worked."

Apple hasn't exactly "let this integration slip" - they just outright killed iDVD years ago.

Ended up giving up on iDVD. I used Bombono's free version for Windows which kind of sucks but got the job done.
