Advertisements I now have two HR21 DVRs and they're ok (not as good as TiVo, but hey...). However I've noticed that sometimes when changing the channel, the "searching for signal" comes up for awhile. Today it took about 10 seconds to lock onto the local Fox channel to record Prison Break. My signals are all in the high 80s and low-to-mid 90s (with some even at 100!). And once the channel is locked in, there's never a problem - no pixelation or anything. So what's the deal? Anyone else experience this?
