That's because the OS re-interprets the alias to point to a valid file 
reference, and returns that instead of the alias path. You'd need to do 
that yourself if you want to script it, otherwise you won't get a valid 
file name.

The dimming of certain file types is just a selector filter within the 
Open File dialog, it has no bearing on what files can be chosen or 
opened by script.

I think the problem you are having is that the alias is interpreted by 
Rev as an actual file instead of a pointer to a file. Since the alias 
file itself isn't an mpg, you get the error. Try using the 
aliasReference function to get the real file name and set your player to 
that instead.
