TP 600E,770 - Some MPEG2 NTSC files cannot be played smoothly with DVDExpress

Applicable to: World-Wide

Symptom:
Some MPEG2 NTSC files cannot be played smoothly with DVDExpress version 4.00.018.1.4 or later.

Configuration:
ThinkPad 770 series or ThinkPad 600E running DVDExpress version 4.00.018.1.4 or later. To check your version of Mediamatics DVDExpress:

• Click the Windows Start Menu
• Select Programs
• Select Mediamatics DVDExpress
• Click on Mediamatics DVD player
• When the DVD control menu opens select the DVD options icon (picuterd as a check mark, bottom button on the left side column.
• Once the options menu opens, look on the About tab for the Build version number
• If your build is version 4.00.018.1.4 or greater, this patch applies. Earlier versions of DVDExpress do not apply.
• Select OK when finished to close options menu.

This patch applies to MPEG2 files have incorrect SCR (System Clock Reference) values. The old MPEG-2 splitter in DVDExpress did not check the SCR values in MPEG2 files and could play them correctly. However, the new DVDExpress uses the Microsoft MPEG-2 splitter and it checks the SCR values to support non-linear MPEG2 files that are used for DirectShow based games. As the result, the incorrect SCR MPEG2 files cannot be played smoothly by the latest DVDExpress.

Solution:
Apply the patch mmosplit.dll. This patch allows existing MPEG2 files with incorrect SCR values the older DVDExpress would play to be used with newer version of DVDExpress.

Limitation: The support for incorrect SCR MPEG2 files and the support for non-linear MPEG2 files are exclusive. If a user applies this patch, the DVDExpress cannot support some DirectShow based games with non-linear MPEG2 files.

Patch Installation procedure:

1. Create a DOS window and change to Mediamatics DVDExpress Mpeg2 directory (e.g cd c:\ProgramFiles\Mediamatics\DVDExpress\Mpeg-2)
2. Unregister existing splitter by the following command. <winsysdir> is the Windows system directory such as \WINDOWS\SYSTEM.
   <winsysdir>\regsvr32 /u mmsplit.dll
3. Register the attached splitter after copying it to any directory
   <winsysdir>\regsvr32 mmosplit.dll
   

1. Unregister patch splitter from its directory
   <winsysdir>\regsvr32 /u mmosplit.dll
2. Register the released splitter after changing to the Program Files\Mediamatics\Mpeg-2 directory
   <winsysdir>\regsvr32 mmsplit.dll
   

Obtain and apply the patch mmosplit.dll from the Mobiles Private area on the FTP server. Contact the IBM HelpCenter in your area for information on obtaining this patch. Click here for a listing of IBM HelpCenter Phone numbers.
