 Scanning type for AVI container is always set to "progressive" no matter
 of interlaced/interleaved type of video stream stored in.

 Example:
 ffmpeg -i input_files -c:v mpeg2video -flags +ilme+ildct -top 1 output.avi
 or
 ffmpeg -i input_files -c:v dvvideo -flags +ilme+ildct -top 1 output.avi
 or
 ffmpeg -i input_files -c:v mpeg1video -flags +ilme+ildct -top 1 output.avi
 or
 ffmpeg -i input_files -c:v mpeg4 -flags +ilme+ildct -top 1 output.avi

 Always the scan type for output.avi files is set to "Progressive" while
 the store metod is "Interleaved fields, Bottom Field First".
 No matter of input_files: dvvideo (interlaced, bottom filed first)
 interlaced mpeg2 or any other type.
