[MPlayer-users] how do I enable mpeg-pes?

[sean]

When I start mplayer on an mpeg2 vob I get:

Playing Clip_04.vob.
MPEG-PS file format detected.
VIDEO:  MPEG2  720x480  (aspect 2)  29.970 fps  8500.0 kbps 
(1062.5 kbyte/s)
==========================================================================
Opening video decoder: [mpegpes] MPEG 1/2 Video passthrough
VDec: vo config request - 720 x 480 (preferred colorspace: 
Mpeg PES)
Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
The selected video_out device is incompatible with this codec.
Try adding the scale filter, e.g. -vf spp,scale instead of 
-vf spp.
VDecoder init failed :(
Opening video decoder: [libmpeg2] MPEG 1/2 Video decoder 
libmpeg2-v0.4.0b
Selected video codec: [mpeg12] vfm: libmpeg2 (MPEG-1 or 2 
(libmpeg2))

But:

mplayer -vo help | grep mpegpes
         mpegpes Mpeg-PES to DVB card

And at the end of configure:

   Enabled optional drivers:
...............
     Audio output: alsa esd arts oss sdl mpegpes(dvb)
     Video output: xvidix cvidix md5sum sdl gif89a pnm jpeg 
png mpegpes(dvb) caca aa opengl dga xvmc xv x11 xover tga


What else needs to be done?  Do I need some config file that 
has -vf spp,scale? Is that better(?) and libmpeg2?
