Video Scrubber Bar & Rewind using MovieTexture?

I am wondering whether it is possible to create a video scrubber bar so that you are able to move to a specific time spot within a movie playing on a MovieTexture? I was thinking that using the Unity 4.6 slider tools there may be a way?

So far I have a video playback system that supports fast-forwarding, pause/play, and stopping using the technique outlined in the below thread:

But I am also curious if it is possible to create a rewind effect in the same way that fast-forward works? I have tried but wasn't able to get it working properly. Thanks for any help!
