I used to solve such[1] problems using -J fps.

You should give the import and export frame rate on the command
line:

transcode -x mplayer -i <file> -f 20.000 --export_fps 25.000,3\
          -J fps -o Newfile -y <YourChoice>\
          <extraOptionsForYourEncoder>

I have choosen -x mplayer, as you suggested it. Dunno if you will
need it.

If it fails have a look at -J modfps, too.

[1] Never had a file @20fps though. But mjpeg @15 fps is quite
    common for some digicams, which fps could handle.

BTW: The sound looks somewhat crazy 48000,_0_,6 ... dts?
     Probably it needs some extra treatments. If in need try 
     -x mplayer,null -y <YourChoice>,null
     mplayer -dumpaudio -dumpfile audio.ac3
     and mux it back later.
