avi file duration, frame-count etc

[Rgemini]

Does anyone know of a simple Python module that would let me read out the 
playing duration of an avi file? Or a way of getting the information using 
the os? I use WinXP & Win98.

The Multimedia Services documentation doesn't explicitly mention video files 
and Mr Google wasn't as helpful as usual ...

Rgemini, who shall remain sigless.
