Does anyone successfully run Nero Recode2/Showtime2 on MSWindows Server 2003? Nero support in Germany hasn't figured out what the problem is.

Showtime does not play any MP4 files and always says "Error reading file." It does not matter if the MP4 files were created by Recode2 or some other encoder. But Apple Quicktime 7 can play the same files.

Also, Recode2 on Windows Server 2003 does not create any valid MP4 files that any player can read.

The steps I used are:
#1: Install MS Windows 2003 Server on fresh formatted disk
#2: Install Nero 6.6.0.14 (Update Package 1)
#3: Install NeroVision/Recode/Showtime 6.6.0.14 (Update Package 2)

So I used the codec that is typically installed with the scenario above.

It also doesn't matter whether I apply SP1 to MS Windows Server 2003. It still doesn't work. But if I reformat and install it on MS Win XP, it works.
