i have tmpgenc xpress v4.0.3.169 and whenever i start a new project and choose a video (usualy xvid avi) to add to the project it takes up to several minutes to load into the project! it didn't do this for at least a month after i loaded xpress 4 into my computer.

by contrast i also have xpress 3, and the very same videos load instantly when i ad them to a project in xpress 3 still.

why is it taking so long for xpress 4 to load a video into the project and how do i fix this?
