No need. I FINALLY got it to switch SAP channels. It seems I was too impatient. There is a significant time lag between choosing the Spanish setting and having it kick in. I had already deleted my original problem recording. But I got a more recent one that was recorded correctly to switch back and forth between the two channels with the expected results.
I did play with it late last night and discovered the same thing. I found a show where the English and Spanish programs were different (actually the Spanish was mostly silent, except for a few commercials), hit record, then went back and played the recording, hit pause and switched back and forth. It would stay on the original audio for a few seconds, then switch. Apparently it reads the audio into a buffer, and only honors the switch when it has to go back to the recording to fetch more audio.
So now we know:
1. The DTVPal does record all audio programs, so you can switch between them during playback; BUT
2. You can only switch by language, so if your stations broadcasts two audio programs but labels both of them English, you're SOL; and
3. There's several seconds of buffered audio, so if you switch during playback, the change won't take effect immediately.
