Did you find an answer to your other question, as they are related
There is no Microsoft implementation of directshow for .Net but there is this library: http://directshownet.sourceforge.net/ which does all the hard work, everything you need is there including samples.
There are alot of tutorials with source here also: http://www.codeproject.com/cs/media/

First we need to know what format the video is encoded to Let's assume that it is uncompressed AVI (the lingua franca of video on windows).
An AVI video has multiple streams...at the very least two (one for audio, one for video). In order to access the stream you can enumerate through them and check what kind it is. All of this is available through Directshow or through VFW apis. I'm not sure if there is a managed code version of either api so you may have to use VC++ to do what you want.
