Assuming your PBS station has the channels labeled correctly, "English" should have the full audio and "Spanish" should have the "natural sound" (background audio only). Unfortunately, to be sure they're correct, you'll have to wait until they're broadcasting a show where the two audio programs are different, then switch back and forth. If they're backwards, you'll have to get back with your PBS station to get them corrected.
It'd be nice if the DTVPal recorded all audio programs for the channel, and let you choose the one you wanted at playback time, but I'm pretty sure it doesn't do that.
As best as I can tell the DTV pal does record all alternate audio tracks and you can select anyone during playback. However, my PBS station labels both audio tracks as English. This seems to confuse the DTV pal and it does not recognize the second audio track. On my NBC Channel the secondary
audio track is labeled Spanish on the Sony TV, but is listed as unknown on the DTV pal.
Glad to hear the DTVPal does that! Knowing that, I suspect the problem is that both audio programs are labeled "English." I've had problems with stations that do that, and not just with the DTVPal. Most tuners will toggle between all audio programs, even if several are the same language, but my old Samsung DT260F STB couldn't select among multiple "English" programs either. Like the DTVPal, I could only pick the program by language. If the DT260F picked the "wrong" English program, I was just SOL on that channel.
For that reason most stations label their audio programs with different languages now, even if they aren't actually in different languages. But your PBS station seems to be an exception.
My guess is that the ATSC standard wasn't intended to support multiple audio programs in the same language, and a few tuners (including the DTVPal) built that assumption into their products. So the only solutions I can think of are: 1) explain your problem to the PBS station and see if you can get them to relabel the "natural sound" program as a language other than English (it was intended for dubbing, after all); 2) delete the station and add it back, hoping the DTVPal picks up the "right" program this time (that sometimes worked when my Samsung had this problem).
Not sure why the DTVPal lists Spanish as "unknown" on your NBC station. The labels are standardized one-byte codes, IIRC. Maybe ATSC has added a second code for Spanish recently? Someone would need to examine the data stream with a computer program like TSReader to know for sure. Trip's rabbitears.info site has TSReader data for many stations; you might check your station at his site.
