Strange error message on streaming site - could not load the manifest file
I am getting this error message when I try to download free content from the site of a broadcaster:
"Could not load the manifest file. Make sure the source is set correctly and that CORS support is enabled."
I have been downloading the daily TV news broadcast from this site for a couple of years. Anyone know what this means?
