How to change video position?

I would like to be able to control the speed of a video clip and also step through it frame by frame. When I try to use vv.position=vv.position + 100 for example, to step 100 msec forward, the video position always returns to the beginning.
Does anyone know an easy to alter the playback speed of a video? My videos clips are not streamed - they are built into the application. At the moment I am using a timed delay to pause and restart the video to control its speed but I'm sure there must be an easier way.

Paused before position change

Thanks for the reply. Yes, I did this:
vv.pause
vv.Position=vv.Position+100
vv.play

Video position resets to the beginning of the clip.
I think it could be a timing problem. I want to show the new position as a still frame so I do this:

vv.pause
vv.position=vv.position+100
vv.play
vv.pause

Maybe I need to allow more time for the new position to be rendered?

Thanks very much Erel, that really helped.
This works pretty well for incrementing clip position:

vv.pause
vpos=vv.Position+1
vv.play
Do While vv.position <= vpos
'wait
Loop
vv.pause

Decrementing is another problem...
