I was going to give you some indications of how exactly to define "Enqueue" for .Avi or .Mpeg or .... in Windows, but first had a look if this was perhaps explained before in this forum .... and yes:
If you use Search button with "Enqueue" as a search key and subsequently look for the post with topic "Enqueue Shell Extension" you will find an illustrated explanation of how to do it.
Success!
