Well one of the main points why to have this mplayer is to not to use dsp for video because it is overused and cannot cope with higher bitrates/framerates together with decoding mp3 audio. If you want this just use the default video player by Nokia. I think the answer to your question is no.

However it would be interesting to add ogg support to default video and audio player (=to gstreamer) as described on maemo.org here http://www.maemo.org/platform/docs/m...g_started.html . This can move audio decoding to main CPU if you encode it as ogg and thus let DSP decode video a bit faster. But this would not solve problem that the dsp video codecs are a bit picky.
