I am considering adding a roku so I can stream Netflix with Closed Captioning. I am using a wirless router for my Tivo connection and sending the signal trhough a Denon receiver with HDMI. Can I add a Roku using the same router and a different input path. If possible, how would I do this? Are there any other advantages that I would receive with the Roku. I do not want to give up Tivo. I am now very pleased with it and don't want to screw anything up. Roku support was useless. I would appreciate any help.
