Are you referring to the Soundbar Vizio S4251w-B4 , TV Sony XBR 65X 850C
or the Direct TV Genie HD DVR Receiver which I think is a HR44/200? At
least that is what I have written down.
I'm guessing that only Vizio TV remotes can control Vizio Soundbars. The
problem with that most people probably do not use the TV remote but rather
the service provider's remote. At least I do. The Sony remote is going into
a box.
