Nah, I ment that the steps are so big that there's no MPEG-style motion
blur.

Yep, nothing serious, but still visible.

Yep, this does look good, certainly the best MPEG-1 I've ever
seen...Hey, wait a minute, I just watched it again and found out why it
looks so good:
Selected video codec: [ffmpeg2] vfm: ffmpeg (FFmpeg MPEG-2)
So I re-checked:
aero@groath ~ $ file ~/Example.mpg
/home/aero/Example.mpg: MPEG sequence, v2, MP@ML progressive Y'CbCr
4:2:0 video, LD-TV 640P, 30 fps
Seems that the MPEG-header on the file I got says it's MPEG-II with 30fps.

I even saw them on the first time I watched it - my eyes are getting
cranky about those :(. I think I'll need to watch overcompressed JPEG's
and FLV's for few months to get back to reality.
