Dual Tuner: A tuner picks one channel out of all of your available channels. This allows you to view a single channel and to change channels. “Dual tuner” means your DIRECTV DVR has two tuners. It can pick out two channels at once, allowing you to record programs on two channels at the same time.
Multiswitch: A multiswitch lets you use the signal from one satellite dish antenna for more than two TVs. If you currently own a Dual LNB dish that is connected to two televisions, a multiswitch will allow you to connect two cables to your new DVR as well as one to a satellite receiver on your second television. If you own a 2 or 3 satellite dish antenna, your DVR will not work unless you have connected a multiswitch with at least four inputs and two outputs.
Access Card: Your access card contains information about your DIRECTV programming subscription. It must be properly inserted and activated for your DVR to work.
Transponder: A transponder is a piece of radio equipment on a satellite. The DIRECTV transponders receive information from DIRECTV and rebroadcast it to your satellite dish antenna. Each transponder rebroadcasts a different set of channels. If the DVR does not receive a signal for an individual transponder, it will not be able to show that transponder’s channels. Each satellite may have a different number of transponders on it.
