I'm in the Rapid City, SD area, and attempting to pick up the local Fox affiliate on my Series3 HD, and am having no success. I called up the station, and they're saying that they can pick up their own HD feed OTA just fine. I get a signal strength ranging from 90-92%, which should be more than enough, but I get a solid black screen instead of a picture. I can get the other 3 HD locals (CBS, ABC, PBS) just fine, however. I've tried looking at the Diagnostics screen, and when the channel is tuned, it shows some of the following information, in contrast to other local ATSC channels: Program Lock: No PCR PID: - Audio PID: - Video PID: - The rest say "Yes" for "Program Lock", and have differing numbers for the PCR/Audio/Video PID fields. Is there any way to determine more about why the tuner isn't successfully getting a Program Lock? I still think it's something specific to the station, but without more information to take to them, I can't prove anything. The ATSC channel number is 7-1, which is mapped to channel 18. If anyone else is from the area and has experience to compare, it'd be helpful.
