While working in Video Factory I am starting to get the above referenced error. When I place a clip into the Trimmer the program atempts to build an Audio Proxy File. In the past this has not been a problem. Now I get the error, "Stream Could Not be Read", at the end of the building process. Does anyone know what causes this? Each time I open my project the program atempts to build a proxy file, but it is unsucessful. I am still able to playback my project, but now it is choppy, not as smooth as before. Will this affect my final cut when I render the project?
