known bugs but not fixed

• 17/Sep/2002, sometimes, client machine goes to freeze during the playback. At that moment, it reports buffer overflows
• if you hear any clicks or unsynchronizated sounds, reload alsa setting by using alsactl command.
• sometimes, either video or audio stream loses many packets
