Viewing major network shows and dvr programmed shows
Can you still view programs on the major networks and watch recorded programs off my dvr?
Yes. The Roku will connect to you TV via an HDMI port on you TV. You other devices will connect via other ports on you TV, ie HDMI, Coax, Composit or component ports. Your TV will allow you to switch "sources" so you can choose from which device you will be viewing content.
Hope that answers your question.
