25 * - lots of messages still need to be handled (cf FIXME)
26 * - synchronization between audio and video (especially for interleaved
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
32 * - some files contain an index of audio/video frame. Better use it,

34 * - stopping while playing a file with sound blocks until all buffered
35 * audio is played... still should be stopped ASAP
