on which version of ffmpeg and mplayer should this work?

I am using ffmpeg-0.8.8-1.fc16.x86_64 and
mplayer-1.0-0.128.20110816svn.fc16.x86_64

ffmpeg -i out.mts -vf "scale=720:576,tinterlace=5" aaa.mp4 
says:
No such filter: 'tinterlace'
Error opening filters!

after reading  man page I tried:

ffmpeg -i out.mts -vf "scale=720:576,mp=tinterlace=4" -vcodec mpeg2video -an  aaa.mpg

(my mencoder only knows about tinterlace=4 and audio disabled because
focus is on working video first :=)

but there is no usable video. see below:

PS: how to get rid of the  configuration: --prefix=/usr --bindir=/usr.... output?
    redirecting stderr to /dev/null also redirects the quetion about
    output file overwrite...
