Just purchased TCL 6 55R635. I have attached an old VCR composite output, Panasonic Hi-Fi Stereo, to the TCL composite 3.5 input. I had to have the special adapter, 2 different versions, one with ground next to the connector housing and one with video next to the housing (TCL version). I have the component output of my DISH Rcvr wired to the input of the VCR. Viewing DISH through the VCR port is fine. I can record, but when playing back the recording the video is slightly shaky. Sound is fine. I have tried different tape recording speeds, does seem to have an affect.
