I live west of Washington DC, 4.1 is my local NBC affiliate. The DVR has started trying to record from NBC 8.1 (Richmond, 100+ miles away), which fails due to weak signal. I'd like to know how to correct this, and even better prevent recording from either 8.1 or 2.1 (Baltimore).
I'm pretty sure this started over the weekend when I updated my network and the IP for most devices changed, including the HDHR and Mac hosting the DVR. Everything had been flawless for a few years before that.
