Scrolling through images during PP show

[DORI]

Dear All,
I am wondering if there is a way to scroll through a video clip (back and
forth) by manually sliding a scrollbar control to left and right during a
PowerPoint show? The video clip includes about 150 frames (640 x 480).
I inserted a WindowsMediaPlayer control to slide#1 but I could not scroll
through the images as it only show the last frame when I move the "seek"
button to different positions.
Any idea or suggestion on how I can achieve this is much appreciated.
Regards,
DORI

Here is what I have come up with so far:
---------
Private Sub ScrollBar1_Scroll()
ActivePresentation.SlideShowWindow.View.GotoSlide _
ActivePresentation.SlideShowWindow.View.Slide.SlideIndex
Set Image1.Picture = ImageList1.ListImages(ScrollBar1.Value).Picture
End Sub
Private Sub ScrollBar1_Change()
ActivePresentation.SlideShowWindow.View.GotoSlide _
ActivePresentation.SlideShowWindow.View.Slide.SlideIndex
Set Image1.Picture = ImageList1.ListImages(ScrollBar1.Value).Picture
End Sub
----------
Problems:
1) Although this will scroll through the images but there is a delay between
images (about 0.5 second) which makes it too slow. Is there anything that I
can do to speed up the scrolling process?
2) I am also using the scroll event but it seems that I have to let go the
left mouse button and then click and drag it again to go to the next image
which is working like a clickable button not scrolling. Any solution for that?
Thanks very much for any help.
