Ah that's nice, I remember the win3.11 speaker.drv with which you could play through the speaker. Full color video with audio is a bridge to far with a 386 i think unless it's something like a 320x240 mpeg-1 with low bitrate audio, or that low bandwidth codec realvideo. Did the DVD decoding run on a 386? In any case it's indeed amazing that mplayer has been ported to dos.
