set_time(milliseconds) while paused

[speedyrazor]

Hi, I have a working VLC player via Python and wx.python, but I am trying to add in frame accurate seek while paused. Currently I can't get this to work accurately, it seems very sporadic and jumps around. So I am trying, while paused, specifying set_time(milliseconds). I see there is a next_frame but this is obviously very limited.
Any suggestions please?
