Hi everybody!
I have a simple case for you: when I open my Vegas 4.0c and I try to drag and drop (or simply open) an avi file to the main board, I just go with one file with most of the avi files I have tried.
It means that the audio track cannot be determined.
I have already tried to reinstall all the audo mp3 codec nedded, but nothing seems to work!!
What can I do?

thank you all in advance for your help
