When you load up your MM2, you cannot see a trailer and said
something to do with IV50 codec.
The solution is to run cmd.exe in administrator, then key in
this command in bold:
regsvr32 ir50_32.dll (For Windows XP or above
AND 32bit flavor only)
OR
cd C:\Windows\SysWow64 (Change your System32
directory to point towards the 32bit one, instead of the 64bit one
because the codec dll is in 32bit and of course substitiute the C:\
to the actual windows installation directory. Also, the Windows
folder may varies as WinNT under some cicrumstances)
THEN
regsvr32 ir50_32.dll
Notes to 32bits user. If you see your command prompt not in
C:\Windows\System32, you will need to perform the cd command as per
64bit instruction, except substitute the SysWow64
to System32.
This is the way to register the Intel Video 50 Codec without any
downloads / installation and being able to watch the trailer.
Probably it does not affect the gameplay, but I fix it before I
start the game. Also, for my Windows 7 X64 (64bits), it flickers a
lot when loading the program, where other games do happen as
well.
