AVI, I believe is a proprietary format, owned by Microsoft. You may have better luck finding a C# class that can handle it. Microsoft typically gives you something like a 30-90day trial of their .NET development environment.

Might not be a bad way to learn C#.

IMHO, C# was invented because Sun Microsystems and a judge told microsoft to quit messing with Java.

It's not a bad little language, although lacking the elegance of perl, and doing several things that seem fairly strange and are probably meant to say 'THIS IS NOT JAVA!'

I took a quickie seminar in C# last year, and it was there that I was introduced to the Orwellian term microsoft was casting about as they evangelized their .NET platform:

Unmanaged Code

Referring to code that was found in traditional .obj, .o and executable files, but in effect referring to anything that wasn't produced with .NET.
