Please enlighten me on this issue. I am in the Greenville, SC-Spartanburg, SC - Asheville, NC area. I receive off air channels via an outside antenna from Greenville, SC (4.1, 4.2, 4.3__21.1, 21.2, 21.3__29.1, 29.2, 29.3), Spartanburg, SC (7.1, 7.2, 7.3__64.1, 64.2), Asheville, NC (13-1, 13.2, 13.3__33.1, 33.2, 33.3). I have this outside antenna amplified and the output signal, split....one link goes to my HDTV and the other link is connected to my DirecTV receiver (HR20-700). It is configures this way as to utilize the picture in picture feature on the HDTV. I can receive ALL of these channels via my TV but can not receive 29.1, 29.2 or 29.3 via the DTV receiver. This channel is pretty close, so reception problems do not seem probable. The Asheville, NC stations are the furthest away (~50 miles). This is perplexing as these channels were received by the DTV receiver previously.....but now after re-setting, these channels do not show up on channel line up on the DTV receiver. I do receive channel 29 via the DTV receiver. It has been like this for a few months. I have re-set the receiver numerious times. All connections are secure. My antenna and amplifier are in the attic. The splitter is under my home, so water/bad weather can not effect them. Any suggestions?
