Yup, I do have an HDMI connection. I don't have my PC hooked up to a wireless connection, just a high speed cable modem with an ethernet cable.
I thought if I got a longer ethernet cord I could un-hook my PC's present ethernet connection, hook up a longer ethernet cord from the modem to the Roku, then hook up the Roku to the TV with an HDMI.
I wanted to keep things as simple and inexpensive as possible until I see if the Roku works as I'm hoping it will.
Do I have to have my PC hooked up while I'm using the Roku on the TV? If so, I guess my idea won't work...
