Ah, you got trapped by perhaps the greatest Python syntax trap.  What
you have given to typeList is NOT a tuple of tuples: the outer set of
parentheses are interpreted as grouping parens and are discarded.  You
have it a list with two entries, which is what it displayed.  Try this:

     file = EasyDialogs.AskForFileOpen(
        defaultLocation="c:\\",
        typeList=( ('Video Files (*.avi,*.mpg,*.mpeg)',
'*.avi;*.mpg;*.mpeg'), )
    )

Notice the extra comma inside the outer parens.  That's the key.
