So I watch my 25 fps DVD on my 60Hz LCD monitor... For now lets assume everything is progressive scan.

It seems that current DVD programs (and all media players on PC's, like youtube, vlc, etc.) just show the exact frames from the source video, and don't do any frame rate conversion.

Surely this leads to unnecessary jumpynessjumpiness? Some frames show for 2/60 seconds, while others show for 3/60 seconds? The effect seems even more noticablenoticeable when the frame rate is close to the monitor refresh rate, such as 29 fps, where noticablenoticeable jumps can be seen every minute or so.

Are there any media players that use temporal interpolation through motion estimation to convert the frame rate during playback? (like this: http://compression.ru/video/frame_rate_conversion/index_en_frcn.html)

Thanks Oliver
