Stefan, are you sure there is really audio after the first few seconds? In a test file I created, Timecode_test.mov, I found that it created no waveform on the 2 Audio channels on the timeline. When I used "ffplay" to play the file outside of Cinelerra, you could hear no sound.

The embedded waveform seems to be created to only a the first few
seconds of the file after which it is blank. For a wav file it does
appear. I removed the cached files from .bcast5. Any clue what else I
can try?

I have attached a screenshot.
