I have a UHD3000 and a Z9X Pro in 2 different rooms and each their their own hard drive storage attached. I keep the movie rips on both HDDs in sync using a file manager but I also want to keep the customized poster wall in sync. Can I backup the poster wall on one device and restore on another device? Or can I select a network location to keep the settings and both devices use the same location?
May be you want to give my Home Theater DB Tool a try. With the tool you can create a backup with images and settings and restore on an other device.
