Unwanted Audio with DV Capture

Q: I'm trying to capture video to a Movie file using the Sequence Grabber and a DV source. I've created a single channel with a channelType of VideoMediaType and I haven't created a audio channel. Despite this, the Sequence Grabber still captures audio, what's going on?

A: This is expected behavior when capturing in native DV format - the audio data is interleaved with the video. The Sequence Grabber capturing from a video channel therefore captures the audio as well. Remember, you can always delete the audio track from the resulting movie if needed.
