Saved value of deinterlacemode=0 is not honored

OpenPHT: 1.6.2 (embedded Intel) PMS: 1.3.3

Disabling of deinterlacing is not respected in subsequent playbacks.

Steps to Reproduce:

Play an item that has interlacing.
Go into video settings and see that deinterlace video is on
Turn off Deinterlace video
Save settings as default for all videos
Notice that guisettings.xml has a line <deinterlacemode>0</deinterlacemode> (changes to this if previously was different).
Play another file with interlacing
Notice that deinterlace video is back on during playback in spite of above setting.

I didn't notice anything interesting in logs files. Repeating the same actions with the scaling mode is honored in subsequent playbacks.
