for VLC

1. Go to Preference(or hit Ctrl+P)
   
2. Go to Video and set Output to XVideo output (XCB)
   
3. Then set Deinterlacing=Auto/On and Mode=BoB/Linear
   
4. Enjoice
   

if the playback still suck:
- try to check Deinterlacing & Deinterlacing Mode by right clicking the video and go to Video>Deinterlace/Deinterlace mode coz my VLC tend to not save the setting and set Deinterlace mode to Discard when the video is playing.
- try to toggle(On/Off) 'Use GPU acceleration' in Preferences>Input & Codecs.

for Mplayer (basic)

1. Start terminal and type mplayer -fps 60 -vo xv -vf tfields=4 <insert.video.path>

integrate into SMplayer

- note : step 3 for Install patch into mplayer is not needed.

Last note : I've only tested these with my lappy(C2D + Intel X4500MHD). My friend lappy (C2D + Ati 4570). Another friend lappy (C2D + Nvidia G310M). If this method not working for your setup, just Topeka
