Thanks for letting me know that trying out these extra dll’s doesn’t work.

I tried to install the Windows Media Feature Pack to see if it helped, but it wouldn’t install. Maybe it could be hacked to help install some of the missing components such as DVD maker. See http://support.microsoft.com/?kbid=968211. It is interesting to note that this document seems to say that the MPEG2, MPEG4 & H.264 codecs are part of core Windows (i.e. they are present in Windows 7 N which doesn’t have Media Player).

I wasn’t asking for solutions on how to playback mp4 files with non-Windows software – I know there are lots of 3rd party solutions, such as VLC player. I thought the whole point of this forum was to get Win2008R2 to work as a desktop solution using Microsoft software as if it was Windows 7, hence my post to point out that there is an unexpected discrepancy with Media Player 12.

I did a little more digging & found that on my Windows 7 PC I have these 3 dlls from Microsoft that are not on the Win2008 R2 PC:

msmpeg2adec.dll
msmpeg2enc.dll
msmpeg2vdec.dll

Strange that Microsoft ship these on Win7 but not on Win2008R2. Why bother to make Media player different? I doubt you can just copy & register them to make these codecs work. I checked in Media Player on Win7 & these dll’s appear under “MPEG/DVD” filters, but are missing on Win2008R2.

The version number for these dlls is 6.1.7140.0 as opposed to 6.1.7600.16385 for most other dlls. I haven’t installed any other software (not even Windows Live) on the Win7 PC, so I know these dll’s didn’t come from anywhere else.
