I called Directv and had them send me a additional receiver (free longtime customer). I told them I had Multi-Room viewing and needed a compatibile model. They said all their models were new and were compatible. They sent me a refurbished H23-600 without a Deca Home Adapter. Will this model work for Multi-Room viewing without a Deca Adapter? I thought only the newer H24 models would, but I wasn't sure about the H23?
