Using Vegas 6 (newbie), great program btw.. smokes Pinnacle 11, anyways .. I have been through some good tutorials specifically Lynda.com 12 hr tutorial.

Now one thing it doesn't explain is once you have done a masking effect or a picture in picture effect, how do you continue working on the project by added another video clip that wont be masked or picture in picture? Not sure if I'm explaining this right, but whenever I try and continue the project by adding another video clip to the timeline whether I put it on video track 1 or create a new one, it does not show up at all in playback.

What am I doing wrong? Any ideas?
