* Find correct method for determining frame rate
  (It's not the mpeg2 framerate code nor the navigation packets time_stamp code,
  because these never match the delivered number of frames. At present the 
  navigation packets table has been edited to make it work)
* Add subtitles
* Add DVD menus
* Number each audio track in sequence, rather than by substream id
* Improve ff and rew
* Add remote control option
* Remake the make file with proper dependencies
* Add the portability code back, and rewrite the MMX enhancements in C...
* Make more video scaling routines, eg aspect correction for 16bit modes
* Fractional full screen pan&scan scaling
* Add more fb support, eg vertical synchronisation, video card hardware
  scaling & yuv conversion (ie implement Xvideo for linux fb)
* Add other sound types, LPCM, mpeg audio, dts.
* Allow selection of interleaved video (ilvu)
* Present interpolated frames at the monitors refresh rate,
* Interpolate interlaced video(yuck) into full rate frames.
