I have a Vizio L32 HDTV that has two RF inputs, one for ATSC and the other for NTSC.I would like to get the Vizio vx37l and receive OTA HD and digital cable but it only has one RF input for ATSC or cable. I called the manufacturer and they suggested running the NTSC feed thru the vcr( which I don't have). Does anyone know of a solution to feed the digital cable to the t.v.? I don't have a cable box or dvr.
