Helpful hints how to use the MPEG driver on Windows NT 4.0
---------------------------------------------------------

When you use the MPEG driver on Windows NT 4.0, the following items
should be considered since some limitations exist in the driver.


1. Any multimedia player application provided by a third party or a
   custom player application created for Windows NT is not guaranteed
   to work with this driver. Only the "Media Player" application
   (mplay32.exe) is tested and verified.

2. If you have already installed ActiveMovie and Internet Explorer 4.01
   included in NT 4.0 Service Pack 3, you will see the following caution
   after installing the MPEG-2 driver. This warning messages is shown at
   next NT boot:

   "Caution
    Some of the file type usually associated with ActiveMovie are
    currently associated with other program. Because of this, you may
    be unable to play certain type of multimedia files.

    Do you want to fix this (by restoring the file type to ActiveMovie ?) "

    Select NO and click "Don't ask this question again".

3. Running more than one video application which shares the same video
   hardware is not supported. For example, while an MPEG file is in
   play, the video capture application will not work. Run one or the
   other at a time. It is also not supported that you will playback
   the ActiveMovie while MPEG media player application is running.

4. When IBM MPEG-2 Decoder is selected on the Device menu on the Media
   Player, opening another Media Player for the Sound/MIDI/Video
   for Windows/CD Audio is on hold. If it requires using other devices
   concurrently with MPEG device on Media Player, select these devices
   first before selecting the IBM MPEG-2 Decoder.

5. Displaying the video window to the external CRT or to TV(NTSC/PAL)
   is supported. When the video is displayed on these screen, following
   limitations apply.

   - 800x600  /16M colors with any refresh rate (video memory limitation)
   - 1600x1200/any colors with any refresh rate (video memory limitation)
   - 16 colors with any resolution, refresh rate

   supported. It is required to pause or stop the playback mode before
   entering into the suspend mode.
