I recently had an HD DVR installed in my front room, I am having a problem with watching live tv while trying to record shows. When the time comes to record that show it automatically tunes to it and I can't change the channel and watch something else w/o getting the message that I have to pick a tuner to change to or I have to stop recording, but I don't show two tuners to choose from. I asked the installer if he needed to add another line to the receiver and he said no, it will work since I have an SD DVR set up in the bedroom. So I guess my question is: What do I need to do to watch live tv while recording something else? and yes I am just recording one thing at a time.
