I'm not trying to replace the audio, I want them both. It would just be much, much easier to edit and sync the audio in PowerDirector if I could remove the blank tracks between the VO track and the video audio track, so I could have:
1. Video Track
2. Video's Audio Track
3. VO Audio Track
nothing/blank
nothing/blank
nothing/blank
etc.
To confirm what you're saying, you're telling me that I can't move, remove, reorder, or delete the FX, Title, and second video tracks (something Windows Movie Maker, iMovie, and Premiere can do)? PowerDirector requires you to have a minimum of eight tracks in the timeline of every project with vertical gaps in between?
