4 boxes 1 TV tuner

[infinitex]

I have 4 openelec boxes, I want to add a TV card in 1 box that supports 4 streams.

My question - is it possible to have live tv on all of the boxes with the 1 tv tuner card? or will it just work on 1?

You can watch with VDR and 1 Tuner on all Boxes the same Transponder / Channel at the same time.

With tvheadend, you can watch or record different channels but only if they are on the same transponder with only one tv tuner.

It Works only with VDR by me.
