Earl - Out of curiosity did you import the audio into a new clean PT template? Was the distortion there from the get go? Are there any plugins on the tracks which are redlining? How does the playback look on the input/output meters? Have you tried having PT re-identify your soundcard? It doesn't make sense that RB and BB would be fine.
Does it playback OK at 16/44.1? or even at 22khz?

Just some thoughts. Let us know if you discover the reason? You know one of basic rules of troubleshooting . . . one you ask for help, you discover the answer yourself.
