Hi Rich, thanks for joining the forum. I’m glad you’re enjoying the archive.
Downloading means you are making a copy and means that we would be distributing that copy. This is not permitted under the statutory webcasting license that our clients use for their archives. So if the downloaded program contains any music, you’ll need a direct license (or waiver) for that music to make the copy.
I can’t explain the options provided by other services. You’d have to ask them. Although not specifically about downloading, this article discusses how different entities have different liabilities. I hope you find it interesting.
