the best way I found is this:
1. install TMPGEnc DVD Author 1.5 and register it (serial)
2.copy folder Pegasys Inc to C:\XPCD\$OEM$\$1\Install\Applications\TMPGEnc-all
3.export reg out of registry (HKEY_CURRENT_USER\Software\Pegasys Inc)
call it tmpeg.reg or so and put it in same folder \TMPGEnc-all
4. if you have ac3 plug in copy the folder TMPGEnc Sound Player to \TMPGEnc-all\Pegasys inc
I call it \TMPGEnc-all because i have TMPGEnc Plus 2.5 also in it.
Put this in your cmd batch file:
ECHO.
ECHO Installing tmpeg_all...
ECHO Please wait
Copy "%systemdrive%\Install\Applications\TMPGEnc-all\Pegasys Inc" "%systemdrive%\Program Files\"
ECHO.
ECHO Registering tmpeg_all...
REGEDIT /S %systemdrive%\install\Applications\TMPGEnc-all\tmpeg.reg
ECHO.
So after end of xp install and rboot you shoud have C:\Program Files\Pegasys Inc
make a shortcut to desctop for the *.exe and start it. Its allready reged.
It works for me that way, hope for you to.
