I am looking for an HD DVR that I can take with me on trips. If a hotel has Dirictv or cable I want to unplug their cable going into the tv and plug it into my DVR and then plug my DVR into the TV. That way I can record, pause, and/or fast-forward programs. I don’t want a recorder with tuners that can pick up OTA signals. Is there such a device available? Than
