Apparently the above is a "stock" message; something triggers the display of the message although it should not appear. My guess is that the file permissions of the .mp4 file indicate the priviledge of execution (click on Properties and have a look at the file permissions). Did you copy the .mp4 file from your Windows partition or are you running it from the Windows partition? > Using the "open with" command works fine, but it's annoying to have to > do that every time. Assuming the guess above is correct, change the permissions so that they match the status of the video files. Simos
