I'm trying to record one show on my HR44 and tune to another channel to watch the news. Instead, I get a screen asking if I want to stop my current recording, and all other tuners are doing a "software download" in the middle of the day! What's frustrating is that I can't tune any of the other tuners (it doesn't give me the option). Is this a 'feature' or bug? How do I prevent this from happening in the future, or prevent it now so I can watch one channel and record another on my 5-tuner HR44?
