iDVD does not recognise mp4 file
Hi,
I have spent the entire morning trying to burn a home movie on to DVD. IT used to be simple, then I upgraded my software (iMovie and Yosemite) and now it can't be done.
I am running iMovie 10.1.1 and iDVD 7.1.2 and El Capitan 10.11.3
In iMovie I export the file using 'File/Share/File...' then selecting 540p format as this creates the smallest sized file (to fit onto the DVD I want to burn to). Once done, I open up iDVD and try to import the new file. It says "Unsupported File Type : Unknown format"
What on Earth am I doing wrong ? I am close to going crazy.
iMac, OS X El Capitan (10.11.3)
