when I build the example project of ARToolkit in Visual Studio 2010, I got this following error :
Error 46 error LNK1236: corrupt or invalid COFF sections C:\Program Files\ARToolKit\examples\paddleDemo\libARvideod.lib(libARvideod.dll) paddleDemo
I followed this tutorial : Tutorial ARToolKit
I cannot reproduce your error as I do not have VS 2010. Also I cannot understand what the person in the video says as I don't understand the language.
However, you can have a look here for more information about how to build ARToolKit5: http://artoolkit.org/documentation/doku.php?id=8_Advanced_Topics:build_artoolkit
Also on this page you find some more information about the simpleLite example.
Also as your question is related to build libARVideo this documentation might help: http://artoolkit.org/documentation/doku.php?id=8_Advanced_Topics:windows_building_libarvideo
On the ARToolKit forum there is a Community-page a the top which leads to a forum which you can use to ask for help about ARToolKit.
Tell me if you got further
