Buffalo Cloud NAS compatible

[Mr1960fm]

Is the Buffalo LinkStation 210 compatible with the HDHomeRun Duo?

I assume you mean SD's DVR or some other app (which are compatible with all the modern tuners), not the duo itself.

Buffalo can be made to work to run such apps but usually one has to dance through many hoops just to even begin to start working with it (to enable ssh, usually by using something like acp commander).
