Issue playing DVDs

Hi

I am having a problem playing DVDs on one of my PCs with Kodi. Basically I insert the DVD in the drive, but nothing happens. I have tried the “play dvd automatically” option and forced region to the correct one, but still no luck. I can see the DVD in the File Manager view. The drive is an external USB drive. The DVDs play fine in WMC, but I would like them to play in Kodi

This does however work on my laptop with the same version of Kodi running, and using the same skin.

Windows 7 64bit
Kodi 17 RC1
Arctic Zephyr Skin

Is there anything else I need to do to enable DVDs loading and playing inside Kodi?

Thanks!
