I don't have Dolby HD, so I won't chime in on that track, but I have fried a tweeter before. No pop or other drama, just stopped making highs. But it was dead, not just on some material. If your tweeter is bad, its bad. Just play some other music and listen closely. You can't hide a dead tweeter on a two-way speaker very easily.
