Prepping for the Feb. 17th switch over. Anyone know how to record the new digital channels onto a blank tape in my old VCR (Signature 2000 -- Model# JSJ 20139 -- this is an old Montgomery Wards VCR). I do not have cable, just an analog TV w/one of those new converter boxes, and an indoor antenna. Everything is hooked up properly according to DTV Answers (http://www.fcc.gov/cgb/consumerfacts/converterbox_vcr.html) but I still don't get any recordings. Any Advice?
