ok well I figured this out. I did not know when you plug something in HDMI1/DVI port on tv hat you have to go in and designate what device you have connected to it. I went into setup and selected Cable STB and now I have my cable box connected to HDMI1 on tv via a HDMI cable. I was thinking this port would only utilize a HDMI to DVI cable, but manual doesnt fully explain this. Now I can connect my dvd player or anything else to HDMI2 port on tv. Before all this when I had something plugged in HDMI1 it did not recognize it so that's where I had got somewhat confused. Glad this is resolved.
