What do you mean precisely when you say it didn't load? Were you able to select the movie in WiiMC's menu selection? This it then just freeze your system, not even attempt to load your file, or give you a code dump?
In the mean time, assuming you are using Winblows, right click the movie and goto it's properties. Goto details and tell me what the screen resolution is for the movie you are trying to view.
Ideally you'll want something around the area of 720x400. Not those exact numbers of course, but anything higher than that usually chugs on my Wii if not crashes is. I.E. Uncompressed Blue Ray rips will not work.
Silly question, but if it was a movie from iTunes, was it a purchased one, or encoded for iTunes?
Anything bought from iTunes won't generally play on anything but an iDevice.
I've never used iTunes HD, but I presume it is comparable with Blue Ray resolutions? I can not be sure.
What Operating System are you running on your computer? If you are on Windows, you can find out for sure using the method I described above.
My first guess, given by what you told me, is that the movie's codec file is not supported, or the resolution is too high.
If the resolution is too high, you can use free software like Freemake Video Converter to easily convert that into a different format and reduce the resolution so that your Wii's meager CPU can handle it. It's a drag and drop program, and all you have to do is select the "to DVD" option at the bottom of the program's screen to convert it to a format that should play friendly with your Wii, without reducing video quality to the point where it just looks horrid.

So if you're still here, I did this with a different movie(use freemake) because it was 1080p and all I got was a folder full of crap hahaa, what do I do here? View attachment 2063
I am terribly sorry, I slightly misguided you. Delete that entire Folder along with all the Folders within.
I meant, and should have said clearly to select your format (I generally use MP4), then in the next window it will say SAME AS SOURCE as the default option. Click on that and select DVD then click CONVERT.
This will produce a single Video file with the MP4 extension and the video will be in a resolution of: 720x576 (yes a little higher res than what I quoted before). If that still makes your Wii crash, chug, skip frames, or what have you, then try TV instead of DVD, but I tend to have good luck with DVD.
Again, sorry for this misguidance, I was going off the top of my head last time.
Thank you, movies are running great now! (:
