I don't have a choice as to which cables to use, my TV doesn't have HDMI inputs, and I have had my Cisco DVR replaced, but that didn't help. I also don't have a choice on 1080i or 720p, my TV will only run in 1080i. I am wondering if there is any way to get a Motorola box to try, or if certain areas have to have certain boxes for whatever reason. Also do you guys think running cat 5 cable to the stb would be better than coax?
