  23  *      - handling of palettes
  24  *      - recording (which input devices ?), a cam recorder ?
  25  *      - lots of messages still need to be handled (cf FIXME)
  26  *      - synchronization between audio and video (especially for interleaved
  27  *        files)
  28  *      - robustness when reading file can be enhanced
  29  *      - better move the AVI handling part to avifile DLL and make use of it
  30  *      - some files appear to have more than one audio stream (we only play the
  31  *        first one)
  32  *      - some files contain an index of audio/video frame. Better use it,
  33  *        instead of rebuilding it
  34  *      - stopping while playing a file with sound blocks until all buffered
  35  *        audio is played... still should be stopped ASAP
