I am using an OTA antenna. I have an analog VCR and a HD digital TV. I am attempting to connect a Zinwell ZAT-970A (with event timer) analog converter box to my VCR using composite R/W/Y RCA connectors. I want to be able to record one channel on the VCR while watching another channel on the digital TV.
Current connection attempt: I have the coax antenna cable coming out of the wall into a splitter. A coax cable from one leg of the splitter is attached directly to "antenna in" on the TV. A coax cable from the other leg of the splitter is connected to the "antenna in" of the converter box. R/W/Y RCA cables from the "out" of the converter box go to the "in" of the VCR. R/W/Y cables from the "out" of the VCR go to the "in" of the digital TV. Additionally, I have a DVD and Receiver connected to the TV via a HDMI cable. Doesn't work. I can't get the menu of the converter box to appear or play the VCR. If, however, I replace the R/W/Y cables with coax cables, disconnect the splitter leg that goes to directly to the TV, and connect a coax from the VCR "out" to the "antenna in" of the TV. It works. The problem with that is I need the TV to work independently (thus the use of the splitter) so that I can watch one channel while recording another.
Cannot figure out why connecting using R/W/Y composite cables is not working. Any ideas would greatly by appreciated. Thanks.
