I have never had my FF and FR buttons to work properly, both in audio, and video. When I click on a button the slider moves foward as you might expect, but the music or video continues to play at the normal speed. It is only when I release the button does it jump foward to the new spot. If I use the Ctrl and arrow keys, video works but it plays at 100X speed. I could not find any settings for this, so I assumed it was a work in progress, and would soon be fixed.
I have WinDV and it works properly, so I guess it is not my computer
CTRL+ARROW for video (all three types - DVD, TV, and video file) works like this:
Pressing the keys once, video plays at 5x speed,
pressing a second time, video plays at 20x speed,
pressing a third time, video plays at 100x speed.
Additional pressing of the same keys will have no effect (video continues playing at 100x speed).
To resume normal play, press the opposite CTRL+Arrow keys, or press Play/Pause keys.
