Ta.
I asked about the problem on another forum and got this reply -

Seems to be issues with the linux driver for these cards.
Open case on GitHub
https://github.com/OpenELEC/OpenELEC.tv/issues/1349

Also suggests that some firmware files have been removed from the build.

Is there a way around it or a solution coming soon? I'm very inexperienced with Linux, etc, so I really don't know how to fix much myself.
