I want to re-broadcast a free Roku channel through a HD to COAX modulator to multiple hard-wired coax televisions in an office. Is this allowed/legal on Roku's service? Can someone point me to the documentation that says this is/isn't allowed? If it's not, does anyone have a better solution? I don't have the ability to install a Roku device on each television and I need them to be in sync with each other.
