When I used my HTL-HD to scan this channel is originally came back with 34-1 as the channel number. My understanding is that there is info on the digital stream that makes it show up as its analog channel number - x. Okay, fine. However, today I entered 34-1 on my HTL-HD and it now displays 4-2. I assume that the PSIP info is doing this.
If the PSIP encoder burns out or something, on Zenith tuners it'll do the physical channel number-2 being that if PSIP is configured correctly, the first stream of video is on x-2 (x-1 is reserved for other things IIRC). Even though the first stream may be on x-2, the tuner can still display it as x-1 because of PSIP.
Two weeks ago my PBS station was remapping to 3.2-6 instead of 15.1-5, and my PAX was on 36-2 instead of 38-1. My PAX is still remapping to 36-2, and the engineer tells me they're installing equipment to do a subchannel, though he has no idea what it is going to show.
Make sure you contact someone at the station and let them know about this. Sometimes they won't even notice sound/PSIP problems.
