iTunes puts my computer in windows 7 basic color mode. It also does not recognize my iPad as viable video source

When I start iTunes on my desktop computer, instantly it switches to Windows 7 Basic Color mode:

"The color scheme has been changed

The following program has performed an action that requires Windows to temporarily change the color scheme to Windows 7 Basic.

Program: iTunes

Publisher: Apple Inc.

Process indentifier (PID): 3296

Windows will automatically change the color scheme back to Windows Aero when this program or other programs performing similar actions are no longer running."

When I close iTunes, it immediately switches back.

THEN, when I try and move a movie I have recently downloaded ("Tangled (2010)" or "Tron: Legacy") to my iPad (1st edition) or iPod Touch, iTunes tells me these devices are not supported:

"Tangled (2010) was not copied to the iPad "My iPad" because it cannot be played on this iPad."

I get the same message with "Tron". This is only happening with the movies I have downloaded after February. All previously downloaded movies work just fine. I have found when I transfer the new files to my laptop and use iTunes on there, everything works normally.

New for today...

When I plug the iPod Touch into the the desktop computer, iTunes locks up completely. I only get it back when I unplug the iPod.

Solutions...

I have done minimal talking via email with iTunes support. They told me to make sure I had the updated version of everything. I had explained in my original inquiry I had done that already. When I replied as such, I did not get a reply. I sent several messages explaining that I have deleted itunes all together from my computer and reinstalled the program from scratch. Finally, I received a second reply to reinstall iTunes.

Also, I have tried several ways of moving the movies over to the iPad and iPod: dragging/dropping, sync, auto sync. I get the same error message every time.

I am more than a little frustrated with Apple's lack of support and hope someone out there knows something that can be done. PLEASE HELP!
