Burn DVD never finishes: waiting for Create Disk to finish
I have a 2023 Mac Mini with an M2 chip, 8 GB RAM, running Sonoma 14.3.1. I want to create a DVD with a 1 GB .m4v video, which I created with FCPX 10.7.1. I tried FCPX's share project to DVD. I selected Output Device to be hard drive, and Build Type to be file. It started processing for a while then stopped progressing at 66%, "waiting for Create Disk to finish." I let it keep running for 2 hours and it never progressed passed that. So then I tried Compressor (v4.7).
I added the same .m4v file to a new batch, selected Create DVD, set the Output Device to be hard drive and the Build type to be file, as before. It progressed for 5 minutes and completed the .m2v and .ac3 files, then stopped progressing with "waiting for Create Disk to finish". I let it run for a couple of hours before quitting it.
I have researched this issue online and found many people have the same problem. I tried all of their suggestions, but nothing works. To me, it seems like this app, "Create DVD" is the problem (I've never found it on my system, and I don't know where it would be.) Does Apple really support DVD/Bluray creation in FCPX and Compressor? Help!
