There is an MPEG animation player on http://members.xoom.com/adderd/.
This is an addon for the Allegro library, so you will need that as 
well.

I don't know anything about AVI's, sorry. My gut reaction would be 
to stay away from them (I don't like closed, proprietary formats,
especially when they are owned by Microsoft :-) but if you really
need to read these files, an AltaVista search turns up loads of 
information including http://www.rahul.net/jfm/avi.html.

The Audiodrive only emulates the SB-Pro 8 bit interface, so you need
to support it to get 16 bit output or higher sample rates. Recent
WIP versions of the Allegro library (see
http://www.talula.demon.co.uk/allegro/wip.html) include a native
ESS driver.

This is way outside my area of expertise, but I can tell you now 
that it won't be an easy task! Good luck: you will need it :-)
