When Importing a Mpeg 4 video, It converts only to a wav file...no video file or display

Question

I need to add some sound fx, and some voice over to a tv commercial.  I usually do this in protools, but I only have access to adobe audition at the moment.  The file is an MPEG-4 H.264, AAC..  After watching some videos all i thought I had to do was import the file into AA 6, and it would split it into a video track and an audio track..  However, I am only getting the audio track.  I checked my -----Preferences > Media & Disk Cache and "Enable DMLS Format Support" was already clicked.  I have restarted my computer and audition,, but still there is no video display, only the wav file audio from the video...How do I do this properly where I can see the video on a track or display, and then have the audio separate so I can edit it,,add fx, voice over, while the video is being displayed?
Any help would be much appreciated.
-thx

Any chance you can share a screenshot of your Files panel?  Video files, if the codec is supported, should import as the mp4 file (which contains the video stream) and a separate audio file is generated.  Both of which can be dragged into a multitrack session, as you expect.
Audition CS6 does rely upon "DLMS" (which stands for DynamicLink Media Server) and can take a few additional seconds to launch.  It's possible this isn't launching properly.  Let's find out. 
Launch Audition, wait 30 seconds or so, then launch Applications > Utilities > Activity Monitor.app   Sort alphabetically and look for a process named "dynamiclinkmediaserver"  Does it exist in the process list?  Does it appear to be failing in some way?  You can also launch Console.app and see if OS X thinks it's failing to launch, and why.
If that seems okay, try opening the MP4 file again, but try the following method:
Click File > Open
In the Enable dropdown at the bottom of the dialog, select MPEG Movie
Select your video file and click Open.
