I usually add all my media into PrE 10 by draging and dropping, however this has not been working for some reason as of late, I drag and all I get is the crossed off NO circle, it is very inconvenient to have to dig through directories to find clips on my computer.
Can you please be more specific about what you're doing?
What are you dragging from what place to what place? Please be very specific, as I know of no area of the program called the Project Manager.
What model of camcorder is your video coming from and what format and resolution is it? How did you get the video from the camcorder to your computer?
