For Apple Mac users looking to download iView shows, I have written a basic AppleScript applet. As with other apps, it uses youtube-dl and FFmpeg and so works on any site youtube-dl handles. It's called MacYTDL.
To use, download the dmg file, open it, read the Help file and save the applet in a favourite place (eg. Applications). It will download and install youtube-dl, FFmpeg and FFprobe as needed. Those components can be updated from within the applet (except MacYTDL at present). It can uninstall itself. Works basically the same way as other apps => just paste a URL into the box and click on "Download".
Has options for downloading subtitles (always in SRT format at present - embedded if desired), file description, file format, download location, overwriting downloads and verbose feedback from youtube-dl.
The AppleScript code is not hidden. So, any keen scripters out there are welcome to improve, change and beautify MacYTDL. Just make sure to send me all the details.
Currently at version 1.2 and requires macOS 10.10. Download from here:
