Hello,
Are you sure it's MVI, not AVI? MVI format is not a video format...
In order to solve this problem please repair AVS files:
1. Close all AVS programs and other running applications.
2. Follow Start > All Programs > AVS4YOU > Repair.
If some of the .dlls are not registered, please make a screenshot of the Repair window showing those files and send it to us.
Regards.
