Just experimented with mplayer a bit more. Looks like it is really mp3 decoding built in mplayer that is very slow (probably because of floating point use as pointed by Frantisek). I tried to encode video with vorbis audio stream (mplayer has fixed point vorbis decoder) and it works a lot better, actually it is even almost watchable

Here is a script I used for encoding video in this test:
Code:
#!/bin/bash

XRES=320
YRES=240
BITRATE=200

mplayer "$1" -ao pcm:fast:file=tmp.wav -vc null -vo null
oggenc -q1 tmp.wav
mencoder "$1" -nosound -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=$BITRATE -vf scale=$XRES:$YRES -sws 1 -ffourcc DIVX -o tmp.avi
mkvmerge -o "$2" tmp.avi tmp.ogg
Usage: ./encode.sh input_file.avi output_file.mkv

Also tested streaming video from http url, it works fine but seeking is not supported. Mplayer also has its own streaming server, probably it should support seeking and work better, but I did not test it.

So I see a good potential for mplayer

edit:
Looks like mplayer can be compiled with libmad which is a fixed point mp3 decoder implementation. So even 'normal' AVI files created by following instructions from https://maemo.org/maemowiki/VideoEncoding could be probably played with mplayer
