In case someone has an old external hard drive from a failed Tablo with videos they need, or you are just interested in sample queries of the Tablo.db… I pushed my Python 3 script to make an .MP4 file from the video segments to github. Obviously if your Tablo is working there are many better ways to do this with apps listed here! But, if the Tablo is dead, this might help save some videos.
I only use Linux, but the DB Browser program I used to query the database is available for Windows and Macs. Python Version 3 is needed and enough skill to change two variables in the code.
I used this to pull videos from a four year old drive (old firmware) and the latest 2.2.30 firmware.
