I'll just add that the deinterlace changes don't affect omxplayer - that should be unchanged.

I've spotted an issue where sd deinterlace may not get the double rate output when "sync playback to display" is enabled. Disabling that options avoid this.
HD deinterlace doesn't suffer from this (it occurs when deinterlace runs too fast and both frames are displayed in the same vsync).

If you use deinterlace please report back. Even if it is "everything is okay".
