I had the bright idea to get my mom an ATV. There are some shows she likes to watch. She's almost 94. I bought it and am getting ready to install it. I bought ATV 4 for myself and am giving her my 3. But I just found out her TV doesn't have HDMI. She has a cable box that has it. Am I screwed? I will start troubleshooting this. Busy at the moment. But there seems to be a digital input but I don't know what kind it is.
