Q: iDVD hangs while processing slides and transitions

Ok, yes, I did that. It still hangs when processing the slides show, sometimes with 7 minutes left, and once with three, it was almost done, but hung.

A little over 70 GBs. If by boot drive, you mean my only hard drive.

I decided to create a very simple completely new project with no music, and three very short slideshows, completely different pics then the other project. It also hangs when it encodes the slides.

I almost always use "soft frame", and did for the first and second projects  that failed. The last simple test one I used "modern".

I've given up on being able to create .img files with iDVD. The last two projects just hang while encoding slides.

Last night I tried to burn and older .img file to a DVD. First, Disk Utility has changed in El Capitan. I found help on how to do it with Finder, but the DVD wouldn't pay in our PS4. The PS4 said it was an unsupported format.

I read about Toast on another string here. Does Toast burn .img files to DVD?

Does it also let you burn iMovie files (which I think can be slides shows)?

I just bought a brand new $2,000 iMac, loaded iDVD on it.. tried for hours to make a DVD, after spending hours making the DVD, of a friend, who recently died...

It hangs on my brand new $2,000 iMac while processing the slides. I promised his sisters I would make them a DVD for the funeral. This is truly horrible.
