Recorded video file does not have right permissions

Hello

I am having a problem with FMS 4.5 .. when a video is recorded, the recorded file is ending up with 760 as permissions. I would like to allow my site users to download their own recorded shows... so the file needs to have a permission of 755 or 666

How i can make FMS save the files with 666 or 755 permissions? I have to do it manually for each file now for them to be able to download but this is too time consuming

thanks
