<p>Where can I find either literature or video demonstration of unit testing applications using VB.NET? As a novice/hobbyist programmer I would like to build a solid foundation in developing applications using the unit testing methodology.</p>

If it helps any, you may want to learn C# if you plan on staying in the .NET world and ever plan to use .NET professionally.  I've answered why
here
.  Now, on to your question: O'Reilly and Associates had an
article on this very subject
recently (if by 2005 you mean recent, but for our purposes, we can call it recent).  You may also want to learn
Nunit
, which is a unit testing framework for .NET.
As far as Books:
Open Source .NET Development
- Covers Nunit.
eXtreme .NET: Introducing eXtreme Programming Techniques to .NET Developers
Test Driven Development in Microsoft.NET
That should get you started.  I don't know whether the code examples are in VB or C#, but if you have a
Safari online
subscription (which I highly recommend), you'll be able to browse these books without dropping money on them.
