mplayer_1.0rc1-maemo.17 has been released:
* Added YUV420 color format support for framebuffer video output ('-vo nokia770'). It works out of the box for N800, but needs a fixed kernel for Nokia 770 (https://garage.maemo.org/tracker/ind...d=164&atid=683). Nokia 770 requires explicit command line option '-vo nokia770:yuv420=1' for enabling YUV420 video output (using it with the default IT OS 2006 kernel will just crash the device). YUV420 format provides 20-30% speedup for video output (overall improvement is only a few percents though as video decoding usually takes much more time than video output)
* Now '-vo nokia770' is temporarily set as default video output for N800 as it lets to have fast video output performance even without xserver patch https://bugs.maemo.org/show_bug.cgi?id=1278)

This is an experimental version (for the reasons explained above), so if it does not work good for you, you are advised to stay with version .16
