I Tivo'ed it on my Series 3 but hadn't tried to watch it yet. I spot checked it and also heard no foreground speech for the first 16 minutes. At that point, it seemed to return to normal. This is from KGO (HDTV version), the ABC affiliate in San Francisco, CA.
Looks like I'll need to turn closed captioning on when I watch it.
Added: Another alternative is watch the show (or at least the first part of it) on
ABC's website . As of the wee hours of Thursday morning, last week's show was still the latest one, but this week's should be there soon.
