[MPlayer-users] Jerky video encoding when using deinterlacers

Greetings all,

I have a rather odd problem.

The video i am trying to encode is 1440x1088 interlaced at 25fps.
Its a HDTV recording.

If i encode with just the VF options of "crop=1424:1072:8:6,scale=1024:576" i
get smoothly encoded video (ignoring the interlacing).

If i then add "pp=md" or any of the other deinterlacers, the encoded video jerks
every ~1sec throught the whole video.

I have tried different lavc options, but they done have an effect.
Only the "pp=md", "pp=lb", etc options cause the jerking video.

Doing a 2pass or 1pass encode does not make a difference.

A CVS version i was using thats a few weeks old had the problem, as does my
current build of todays CVS version.

Any ideas?
