If you have a monitor that you can change refresh rate, you may be able to match multiples of the frame/field rate to that and get it to display smoothly, ie if the original material is PAL / UK rates it may play smooth if you can set your monitor refresh rate to something like 50/75 or 100.

Unfortunately many monitors only support 60Hz so this may not work.
