Though I'm no expert I see nothing wrong here, I also checked whether I had other x264 
installs anywhere else and I don't. I'm stumped.  :)

The only reason I started out to do this is I'm hard of hearing and have to edit a lot of poorly
done subtitle files. I've been doing them by hand and thought I need to install a subtitle editor.
Hell, I could have finished the subtitle by hand by now.   LOL

But I still need to get this or something like it working.

Thanks for the help.
