Video Loading Issues

Cross 3.2.0
Lenovo Thinkpad Edge
Windows 7 Pro 64bit
Core i3 2350M 2.30 Ghz
4.00GB RAM
Intel HD Graphics 3000
I have downloaded the Visual Vibes video files and they all appear to be .mp4 video files.
When I go to drag the file up to the video loading window all I get is a stop sign with a minus symbol inside. I try and drag the file into the audio deck A side I get an unknown file format error.
The video files play fine within Windows Media Center. I'm I missing something here? Any input would help, thanks
