For openmax the settings I am using are :
At Playback Profiles (3/8) screen select "Edit"

1st line Match criteria set to ">="  W: "0" H: 0
2nd line Match criteria set to nothing ie. blank
3rd line Decoder "openmax" Max CPUs: "1" Deblocking filter selected
4th line Video renderer "openmax" OSD renderer "opengl2" OSD fade selected

on Next screen
1st line Primary deinterlacer "Advanced (HW)"   this is probably what is 
missing
2nd line Fallback deinterlacer "Fast (HW)

Mike
3rd line Custom filters blank
