I am interested in taping a few shows and special events with a SVHS vcr. I have a Time Warner box w/ a HDTV decoder box. Do I have to buy a vcr that has both svideo inputs and outputs or can I get by with just an output that goes to the tv from the vcr and a coax or a/v cable set to the input on the vcr and still get svhs qaulity? Hope this makes sense.... P.S. I know, I gotta go the Tivo route soon but do have many old fights I'd like to watch and maybe some new ones to record later. thanks all!
