The Vietnam War (2017) won't rip the main features :-/

[jodrell]

Description of problem or question
Ripping the main episodes, not the bonus features (they work fine) of the 2017 PBS Documentary, The Vietnam War, completes successfully in Handbrake but only takes seconds and results in very small files of black video. Also, Opening the DVD and asking it to scan only the title containing the episode, confirmed using the DVD player app on my Mac, gives me an error saying "No Valid Source Found"

Steps to reproduce the problem (If Applicable)
Open DVD, select Title 36, press start. Wait 10 seconds

HandBrake version (e.g., 1.0.0)
1.0.7

Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.3 High Sierra, Windows 10 Creators Update)
macOS High Sierra 10.13.2

Error message text or screenshot (If Applicable)

Provide a URL from any image hosting site.

Try ripping with makemkv first.

Will try...if I can find it.

If this helps I just tried a Live Preview. It took a hell of a long time but got there eventually. Here's the log for that.

Yup, that worked fine. Thanks for the advice.
