I live 25 miles west of Philadelphia and 50 miles east of Lancaster, PA. With my OTA antenna and the DTC-100, I was able to tune in the analog version of Channel 8 in Lancaster. With the HR-20 when I tune channel 8, I receive the message "channel not available." Because I am in the Philadelphia market, Channel 8 is not among my list of available analog channels. The option to scan for and select off-air channels produces a list of only receivable digital channels. Since I cannot receive the digital version of channel 8, that channel does not show up in my off-air list. So, how do I tune in analog channel 8? I have a 6 year old monitor, the RCA MM36100, that receives an HD signal only through a 15 pin VGA input. I needed to purchase a component to VGA transcoder, the V-Digi VD-Z3 connecting the component cable from the HR-20 and the VGA cable to the monitor. The best picture is with transcoder switches 2, 4 and 6 set in the "on" position. However, there is a noticeable flicker in the image. Any suggestions on how to eliminate the flicker? Thank you.
