Is there a log file for iDVD '08?

The video part is two mp4 files and they have audio along with them. The three slide shows do not have audio, I actually chose not to have audio. I'll correct that and see if I can get it to work. Thanks!

I added audio to the three slideshows that didn't have audio, so now everything has audio, but I still get the same message. Since there's no log file or any more information, I can't tell what's going on.

Everything has audio now. The video files contain audio according to Quicktime Player. Here is the file information as QT sees it:

+File type is mp4 file+
+Format: AAC, Stereo (L R), 48.000 kHz+
+H.264 Decoder, 960 x 544, Millions+
+FPS: 29.97+
+Data Rate: 63.91 kbits/s+

iDVD succeeds on these steps: Prepare, Process Menus, Process Slideshows
iDVD fails when it begins to Process Movies with the same message as above.

Does that information help figure out why it's failing?

I have enough space. I've tried to run this on three different Mac machines (two are Tiger machines and one is Leopard). Here are the machine specifications:

1) PowerBook, 1.67 Ghz PowerPC G4, 2GB DDR2 SDRAM, Mac OS X 10.4.11, 35.24GB Available on main Drive

2) Mac mini, 2Ghz Intel Core 2 Duo, 2GB 667 MHz DDR2 SDRAM, Mac OS X 10.4.11, 100GB Available on main Drive

3) PowerMac, Dual 2.7 Ghz PowerPC G5, 4.5 GB DDR SDRAM, Mac OS X 10.5.3, 53.13GB Available on main Drive

After the failure occurs, with Activity Monitor I noticed the status of these two processes: The ThumbnailServer has pegged the CPU and the EncoderServer says (Not Responding).

I tried going into Project Info at the bottom of the page where it lists the assetts, it shows that the encoding is "Done" on the two movie assetts. I thought maybe there was a problem with the encoding so I changed the encoding to Professional thinking that maybe there was a problem with the encoding process. The encoding changed to two blank bars. After I run the burn, the encoding is still two blank bars and is not marked "Done".

Do I need to put this together with iMovie first? I stopped using iMovie because it seemed like it wasn't doing much and it was easier to just tell iDVD '08 what I wanted on the DVD.

Well, I removed everything and started over. I ran the mp4 videos through iMovie '08 and then into iDvd and after all that, I still got the same error in the same place. At this point, I don't know what else to do.

Well, after a night of sleep I had renewed hope and so I tackled it again. This time I ran it on my Tiger machine and this time I imported each mp4 movie into a separate iMovie file using iMovie version 5.0.2 (111). This time it worked.
