I capture footage from my Canon Hv20/30 and Vegas will not detect scenes. It will capture one long file. Also, each scene captured from my Sony HC1 has fraction of second of next scene. Why???

Same problem here. Used to work but not anymore.

Is the clock in the camera set? The clock must be set at the time of the recording in order for scene detection to work.

Thanks Edward;

That's currently normal. I don't know if/when that will change.
