Microsoft MPEG-4 codec install issues

I took the plunge this past weekend and purchased a Plextor video capture 
device.  It uses WinDVD for the capture.  It works fine except the preview 
window goes blank when I capture and convert to MPEG4/DVX format.  The FAQ on 
their support page says this is a known problem with Win2k and I need to 
install the media player 6.4 codec.  It even has a link to download the files.  
Here's where it gets bad.

I installed (I thought) the codec and nothing changed.  The documentation is 
very adamant about having the latest patches to Windows so I loaded the most 
recent updates including an update to media player 9.  Still no change.  Last 
night I tried again to load the 6.4 codec.  Interesting thing.  The install 
would appear to finish but if I ran it again it would try to install the same 
files and I would get a message that a previous install didn't finish properly. 
 I went through this cycle many times.

Somewhere during this I thought maybe the install file I was using was bad and 
went to Microsoft site to get it.  Noticed there is a different download file 
for media player 7 and above.  Thinking I had at last found the source of my 
problems I downloaded and installed this codec.  Still no joy.  Again, tried 
multiple times.

I have sent another message to their technical support by am expecting to be 
told it's not their problem since it involves a Microsoft codec install.

Any help would be greatly appreciated.
