If MythTV is using any of the normal sorts of video files, they are = already compressed.

I just got done copying the stuff = fromhttps://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/9.0-RELEASE verbatim = into 2 shell scripts to automate the setup, I would never follow any instructions verbatim unless they did _exactly_ = what I needed.

Follow the instructions through a few times by hand. Understand what = they are doing and _why_, then script what _you_ need to do.
