I was visiting here to find out about conversion:
https://support.plex.tv/hc/en-us/articles/201358273-Converting-ISO-Video-TS-and-Other-Disk-Image-Formats
and noticed this dead link related to Handbrake
Related Page: Documentation & Help
(This might be the best link to replace it with? HandBrake Documentation — Table of contents )
This prompted me to try a broken link check. I just used the first Google result which was http://www.brokenlinkcheck.com
[I gave it support.plex.tv]
