I just setup a htpc and it is hooked up to a brand new over the air antenna. On any TV in the house, channels come in great with minimal break up. On MC, a scan for ATSC (only) revealed only 1 channel (and sub channels) out of our typical 10 or so that a TV would pick up on. The channel that comes in works fine for about 10 seconds when I start playing it but then it gradually starts to break up more and more until it's unwatchable (after another 10 seconds). The signal on this channel was reported as 65% on MC. Our other channels show a signal strength of perhaps 30% on our other TVs, but they look fine. Any ideas? I am able to turn the antenna so I should try that. Maybe I should try waiting longer on discovering channels? Just trying to figure this out. Hauppauge 1600.
