I have an S3 Trio64V+ with its MPEG daughter board can someone explain what the MPEG decoder is good for all I know about the decoder is it decompresses MPEG video and audio in Windows like when watching a DVD but is it of any use in dos?

DVD 😀 No.
Its good for MPEG-1, so CD-I movies, VideoCD. There are drivers for Win32 MCI API so any system video player will have hardware acceleration.
You could probably play 'Return to Zork for ReelMagic' and maaaybe couple other FMVs, but not most of them because they usually used custom codecs like '7th Guest'

It could be useful in a 486 or slow Pentium for watching Video CDs. On a fast Pentium (tested with a 200 MHz Pentium) a software MPEG decoder like XingMPEG Player or a DirectShow filter (like the one that come with Windows Media Player 6.x) will be enough.

As rasz has written, it uses an MCI driver, which is a very "high level" framework for multimedia control and dates back to Windows 3.0. Most players use DirectShow to play videos, and I don't know of any DirectShow filter that would make use of this hardware.

I also wouldn't expect ReelMagic compatiblity. I think ReelMagic Windows apps would specifically look for the ReelMagic MCI driver and DOS games would look for a ReelMagic compatible device.

I have a Miro Media View TV card with an S3 Scenic / MX2 processor. The card comes with a DOSMPEG driver, which allows to run games compatible with RealMagic cards.

Below is a list of supported games from the README.TXT file:

III. SUPPORTED REELMAGIC DOS MPEG TITLES
=========================================


3.1 Return to Zork
----------------------------
Run installation and follow the instructions. Choose Sound Blaster
Pro as a sound device. Parameters should be port=220, irq=5, dma=1.

Because of palette switching problem, there are a few areas where parts
of the screen may flicker. This will not effect gameplay.


3.2 Space Ace (ReelMagic ver.)
----------------------------
Change active drive to be a CD-ROM drive and run PLAY.BAT.


3.3 Dragon's Lair
----------------------------
There are two versions of this game. The early version of the game
uses "play-from-file" ReelMagic API; the other - "play-from-buffer".
If there is PLAY.BAT file on the CD-ROM - it is the second version,
if not - the first. Second version of the game can be run directly
from CD-ROM. Simple run PLAY.BAT. Since the earlier version did
not contain this useful file, we provide one (it is called DRAGON.BAT)
on our installation diskette. If you get an "Invalid drive" error,
then modify the line that reads "D:" to reflect which drive is the
CD-ROM.

There is a known problem with the play-from-files version of Dragon's
Lair title in the room Black Knight and the Checkerboard Floor. If the
room starts out with a jump to the right, the room cannot be completed.
There is a mirror image of this room, so you will have to restart the
game and play until you start with a jump to the left.


3.4 The Horde
----------------------------
Install and run. This title will not display MPEG clips if mouse is
not installed. Be sure to have mouse installed.

If the game locks up as you start gameplay, it is an indication that
the sound card was not detected properly. This game is unique in that
it does not allow for manual configuration of your sound card, and
occasionally it will detect the wrong settings. Consult your Sound
Card manuals and adjust the settings until it works properly. You will
know it is correct when a "selection" noise plays when you scroll
through the options on the "New Game", "Load Game", "Quit" screen.


3.5 Lord Of The Rings
----------------------------
It is the most "memory greedy" program so far. Installation guide
suggests the way to install this game. We found that game can be
installed successfully if before MEM.EXE reports more than 580K (593,920
bytes) in Conventional Memory and more than 129K (132,096 bytes) in
Upper Memory. In order to free this amount of space you will have to
remove all drivers and TSRs from AUTOEXEC.BAT and CONFIG.SYS files. It
will also help if you move CD-ROM drivers to lower memory.

Here is the sample of how you can meet memory restrictions on the Compaq
system. The following modifications ot AUTOEXEC.BAT and CONFIG.SYS are
advised (please refer to sample files in section 1.3 of this README file):

CONFIG.SYS:
remove -> DEVICEHIGH=C:\WINDOWS\CPQWIN\CPQCM.SYS
remove -> DEVICEHIGH /L:1,12048 =C:\DOS\SETVER.EXE
edit -> DEVICEHIGH /L:1,14816 =C:\CPQDOS\CPQIDECD.SYS /D:IDECD001
to -> C:\CPQDOS\CPQIDECD.SYS /D:IDECD001

AUTOEXEC.BAT:
remove -> LH /L:0;1,45536 /S C:\DOS\SMARTDRV.EXE /U
edit -> LH /L:1,27952 C:\CPQDOS\MSCDEX.EXE /D:IDECD001
to -> C:\CPQDOS\MSCDEX.EXE /D:IDECD001

You may have to run the game without mouse support. It may not be
possible to free enough memory to run this game on some systems.


3.6 Man Enough
----------------------------
Run installation utility with /A option (INSTALL /A) and follow the
instructions. Choose Sound Blaster (NOT Sound Blaster Pro) as a sound
device in both cases. Put the scroller in the middle of [MIN-MAX] scroll
bar; Scroller [Music-Samples] should be 1/2" from Samples.


3.7 Flash Traffic
----------------------------
Run installation and follow the instructions. Do not try to profile
CD-ROM (cancel it as soon as possible, otherwise it may crash). Choose
Sound Blaster Pro as a sound device in both cases. Parameters should be
port=220, irq=5, dma=1. This game should be always installed after the
driver, since it tries to find driver in path and than hardcodes it in
batch file.

This is nice. I'm curious, whether these MPEG drivers will work with other Scenic/MX2 boards. The VideoLogic GraphicsStar 400 also had these in their package and these are exactly the same files,.

I think this driver is generic for all S3 Scenic/MX2 cards. An identical version of the driver was attached to the Videologig MPEGstar card. The only difference is the READMY.TXT file.
