Yes, but it should not be different in  that regard. It could be the
version of mencoder. I use MEncoder CVS-030208-10:35-2.95.3. 
Or maybe the options you used for the mplayer config.
I use 
./configure --disable-dxr3   --with-xvidcore=/usr/local/lib/libxvidcore.a --with-extraincdir=/root/DVB/include/ --enable-largefiles

Hmm, strange error message.
Maybe there are some libs missing that mplayer needs. Here is what I
get as a result for configure:

  Enabled optional drivers:
    Input: streaming tv-v4l edl tv cdda mpdvdkit2 vcd
    Codecs: qtx divx5linux xvid libavcodec real xanim dshow/dmo win32 libvorbis libmad gif
    Audio output: oss sdl mpegpes(dvb)
    Video output: xvidix sdl vesa gif89a jpeg png mpegpes(dvb) fbdev opengl dga xv x11
  Disabled optional drivers:
    Input: tv-bsdbt848 dvdnav dvdread dvdcss
    Codecs: divx4linux libdv liblzo
    Audio output: sgi sun alsa esd arts dxr2 nas win32
    Video output: bl zr dxr3 dxr2 directx svga aa ggi xmga mga directfb tdfxfb 3dfx



I don't know exactly what libs I had to install to make it all work,
it took me while to get the mencoder the way I wanted.
