I just wanted to update this post since someone else may run into the problem
in the future and they can find this help in the search function of these
communities.
It seems after almost a solid week of looking, tonight I just happened to
get the right combination of keywords in Google search to come up with the
solution.
It turns out the culprit of the problem was my Nero program. I installed it
on the 2nd day after building my PC, but then uninstalled it a day later when
I decided to use a different program. When uninstalling Nero, it seems that
it takes away certain registry keys that Media Center needs in order to
recognize certain video and picture file types. .jpeg and .jpg were 2 of the
picture file types I needed and Nero promptly took them away.
The fix will involve editing your registry or re-installing Vista. Proceed
with caution if you edit your registry. If you want more information on the
problem and the registry keys you will need to put back in your registry,
