I connected my DVD / VCR recorder to my tv with a HDMI cable. DVD plays ok, VCR runs but I only get a blue screen on the tv. Do I need any other cables to play tapes on the VCR ? How about for recording on the VCR or the DVD? The DVD/ VCR is a toshiba dvr620ku. The HDMI cable is connected from it to the HDMI 3 port on a Samsung series 5+ 5500 plasma tv.
