The Animation control supplied with VB (and from various other VB websites) is derived
from the implementation within COMCTL32.DLL. However, this implementation only allows you to
play AVIs with no audio stream. Also, its idea of transparency isn't quite what
you might expect: setting an AVI to transparent only sets one of the colours in the
AVI to another colour, rather than allowing you to draw part of the background.
If you want to play any type of AVI, or you want to modify the contents of the
transparent area, you must load and draw the AVI yourself using the API. Luckily, this API is
easily accessible to VB coders.
