Fix Stuttering issue on interlaced file with a picture structure of type "Field"

Stuttering are really visible on screen, it looks like only the player skip one frame each 2 frames.

A Deinterlacing issue may cause the stuttering. It only happen on file with a picture structure of type "Field". When the picture structure is "Frame" everything is fine.

The picture structure of a file can be gathered using MediaInfo.
Some movies having the issue are the folowing :

Astérix & Obélix contre César (1999) (PAL) (DVD FR)
Astérix & Obélix Mission Cléopâtre (2002) (PAL) (DVD FR)
Shaun of the Dead (2004) (PAL) (DVD FR)

Those movies play fine on Kodi, Emby, VLC etc...
