I live in Washington, D.C., just inside the Maryland border. I am able to get good reception on my OTA local channels when I feed the antenna through my tv (Pioneer 4340), but the same OTA locals are unavailable when I run the antenna through my HD receiver. At first, I thought the receiver was the problem, but I'm now on my third one. I started with a Samsung 360 (from the Directv upgrade special). The Directv installer actually understood the problem and concluded that the receiver must be defective so he ordered me a second one. The second Sammy had the same problem. Now, I've purchased the Hughes 10-250, and I'm having the same problem: the OTA local channels that come through fine when fed directly into my Pioneer's tuner do not come through when fed through my Directv receiver. The channels show up in the Program Guide, but I get either a "channel unavailable" message or a "see 'troubleshooting' in 'messages and setup'" message. Any thoughts? Maybe I need to sit tight and wait for the day when all the HD locals will come through via satellite!
