Asx displays plain text not mms stream

Question

I have used the Mac's Web Sharing Apache server to make a little page that you can click on and loads a asx playlist with a mms entry. This can be played with Flip4Mac on my computer locally through safari or it can be played on a PC with WMP10 or it can be played on FireFox on my mini with Flip4Mac.
However, if I try to access the site http://10.0.5.51/~benjibrown/asxhtml.html
and then click, the next page will load a text/plain version of the asx list instead of grabing the F4M plugin and running it through QT embedded.
Now I though this was perhaps my MIME types being served from the Apache so I made sure to add them in mime.type and restart the server. Firefox can access and play that url fine, it seems only Safari can't get the served MIME type asx and access F4M thus playing the mms. I have reset Safari too, thinking that maybe the cache messed it up.
Thanks

Answer 1

Or you could try this:
To make Plain Text the preferred alternative for viewing messages (which may or may not accomplish what you want), quit Mail, open /Applications/Utilities/Terminal, type the following command (you can just copy it here and paste it in Terminal), and press <Return>:
defaults write com.apple.mail PreferPlainText -bool TRUE
You can revert to the default setting with the following command:
defaults delete com.apple.mail PreferPlainText
And you can reverse the setting regardless of what the default setting is with the following command:
defaults write com.apple.mail PreferPlainText -bool FALSE
