"Problems Importing .MTS Files into Lightworks Pro - I'm trying to import footage from a Canon VIXIA HF R10 into Lightworks Pro and running into an issue. When I import the footage the video imports properly, but no audio comes with it. This lack of audio is evident both when I play the footage back within Lightworks and when I export and play it in VLC. The footage is in a .MTS container with a AVCHD codec."
