I have an older model RCA Home Theater Projection TV that is pre-digital. I have a Tivo TCD652160 hooked to it. I'd like to purchase a Roku stick or other Roku device, but I don't know if it can be hooked into the system. There are no HDMI connections on the TV or DVR. There are two USB ports on the TIVO, but I don't know if they'll be compatible with the Roku. Thanks in advance for the help.
