Well I'm not sure what your video source is but one thing to know about the deinterlacer is that it does not accept deinterlaced video where the fields are not of equal size. So NTSC for example has more lines in field 1 than in field 2. The deinterlacer doesn't like that. The solution is to clip the input video before presenting it to the deinterlacer.
