Unable to Share-output to Apple Devices 720

I've attempted to share a 75 minute video to use with iDVD, but I continue to get the following message:

The operation couldn’t be completed. (com.apple.Compressor.CompressorKit.ErrorDomain error -1.)

In other discussions, the suggestion is to update the OS or FCPX to a newer version, but I have OS 10.10.2 and FCPX version 10.1.4.

Any other things I can try?

I was able to Share to Apple Devices on an earlier, different video, and had no trouble.

Thanks in advance,

Gary
