I imported .wav files that my sound guy delivered to me. When I initially imported the audio files they had the smpte timecode and I was using the timecode to sync the audio to the picture (with the TC slate on the picture).
I noticed the TC was off a bit so I went into Preferences->media and then I switched the intermediate timebase to 23.976. That fixed it. I was then syncing clips and then suddenly the accurate TC went away and now all of the clips start at zero. bummer. Anyone know how to fix this?
