Using a digital video recorder (DVR) allows you to record shows without the challenges that often came with tapes and video cassette recorders (VCRs), such as remembering to put a blank tape in, setting the timer properly and taking care not to record over something you haven't yet watched. Many cable and satellite companies offer DVRs with their service that allow you to record your favorite shows if you can't watch them when they air. As long as your DVR is set up properly, you can easily tape two shows at the same time.
DVRs require the appropriate set up to successfully record more than one show at a time. In the case of a satellite television service, you must have two lines running from your satellite dish to your DVR receiver. This allows the DVR to receive two channels at the same time. Some cable DVRs feature dual tuners inside the receiver, which allows two shows to record at once. If the setup is not correct, the DVR will not record more than one show.
Watching Another Show
Because DVRs have only two tuners that allow them to pick up two stations at the same time, trying to watch a third program while recording two others will not work. Most DVRs alert you when they're scheduled to tape two programs at once, asking if it's okay to change the channel when the recording begins. You can override this and keep watching the channel you're on, but the DVR will not record both of the shows you scheduled.
Some people set up specific shows to record each time they air, such as their favorite series. When your DVR is set up to record every show in a series, reruns of certain episodes may air at different times than usual. This can result in scheduling conflicts with other shows set to record at the same time. As long as there are only two shows set to record at a specific time, you won't have a problem. If a third should conflict with the other two, however, your preferences let the DVR know which shows have higher priority, so only two are recorded.
The only time you can record two different television shows while you watch a third is when you watch something you previously recorded. In that instance, the tuners are both in use, recording two different shows on two different channels. Anything already recorded does not require a tuner, so you can watch a third program while two others record simultaneously without experiencing any conflict.
