My stereo sys only has RCA ports. I have a DVD Recorder that has RCA input & output ports and a Digital Audio Output. I also have an older VCR & a Blu-Ray player with an HDMI. All are connected to an HDTV. Currently using PC speakers with a 3.5mm plug into the headphone jack of the tv. Is there anyway to hook up the TV, DVD & Blu-Ray to the Stereo System?
