according to samsungs online KB:

What Video Formats Are Compatible With My SPH-A900 To Be Viewed With The Media Player In The Mass Storage Profile?

The video formats that are compatible are 3GP, 3GPPI, and AVI. These files should be placed in to the Media folder using the USB Mass Storage browsing capability.
