Thank you Pmos69, that is what I was missing. It showed up on my Xbox and I was able to connect to all the movies and other files. The only other problem I had was that the sound is not working. But, even if it did it would not help as the interface is not easy enough for anyone in my family to use. I think I will just hook up a PC to my TV and use Media Center without the Xbox. It is too bad that MS could not at least replicate the same PC Media Center experience on the Xbox... it is going back to the store.
Thanks again for the answer
