getting timestamp with avireader method

[GoogleCodeExporter]

What steps will reproduce the problem?
1.I write videoframes with ffmpeg with videofilewriter adding a timestamp
2.Also I wrote the timestamp as a tag of the bm  beeing recorded
3.the code would be
Dim ESCRITORZoom As New FFMPEG.VideoFileWriter
image.Tag = new New TimeSpan(Now.Day, Now.Hour, Now.Minute, Now.Second)         

ESCRITORZoom.WriteVideoFrame(image, image.tag)

What is the expected output? What do you see instead?
I dont't know how to read the timestamp of each image as i was reading it back 
through the AVIReader method.  I added a tag to each image that contained the 
timestamp before writing to an AVI file.  But as soon as i read it back through 
the avi all the propertyitems had been cleared down.


What version of the product are you using?
2.2.5
