Ok I see
Yeah I was told I needed the component cable from blu-ray to HDTV so I'm using it. I din't think it's really doing anything but I bought it so i'm using it.
I wish someone would have told me in the beginning or the thread that I only need the digital coaxal and not both coaxal and optical. I would have just bought the coaxal first but I only payed $6 for the optical cable so it's no biggie. I haven't tried the LG app store yet so I don't really know how all that works.
