AviReader - getNext

Question

I'm using SharpAvi's AviWriter to create AVI files. I can get any standard video player to play these AVI files. 20 frames per second with no compression. using example from this link so that seems to be working fine.

failing to find SharpAVi's AviReader anywhere I've resorted to using AForge.Video.VFW's AVIReader but it can only show me a black screen for each frame before index 128 and then if fails to get next frame. the example I'm using is straighforward

// instantiate AVI reader
AVIReader reader = new AVIReader( );
// open video file
reader.Open( "test.avi" );
// read the video file
while ( reader.Position - reader.Start < reader.Length )
{
    // get next frame
    Bitmap image = reader.GetNextFrame( );
    // .. process the frame somehow or display it
}

I have my app's Build set to x86 to accommodate both these AVI apps 32 bit settings. and using AForge.Video.VFW AVIWriter fails to write files with more than some 500 +/- frames.(video player needs to rebuild index and C#IDE "fails opening AVI file".

does SharpAVI have an AVIReader? because I haven't found one.
