Try putting the empeg into pause first. This stops it having to cache the first bits ot the next tracks and allows you to scroll through the playlist faster. There shouldn't be much pause at all when skipping though tracks when paused. I know this isn;t the solution but it will show if the operation is normal.
I agree, 5 seconds should be normal when jumping multiple tracks.
