frankly, id rather do this on a Mac since Microsoft is now making it impossible to get updates for Win7 , strong efforts to “push” everyone to Win10 - the new attempt to be a Mac.
I use the SurLaTablo python script to extract shows from my Tablo. See this thread:
I do it in a cron job that saves the converted files into a Plex folder, where the Plex server automatically finds them and makes them available to stream. It’s all running on a Mac mini.
