“First thoughts are ...”
Windows cannot read iOS formatted discs!
That was my thought as well. I could imagine:
- disk not in standard DVD format
- disk session not closed
- media is using codec not available on PC by default (VLC is a free download that could be used to play it)
- filesystem on disk is MacOS formatted and PC can’t read it.
- error in disk writing could cause problems
- PC’s disk reader has problems with this particular type of media (more frequent with older devices)
