Kind of --
As long as you use two seperate media playing programs, you should be fine. On my computer, I can run Windows Media Player and Mediaplayer Classic at the same time, one a dual-head video adapter.
Two sessions of Windows Media Player running simultaneously didn't go right, but I don't remember the specifics.
However, even with seperate media playing programs I did notice one issue: only the first instance (of whichever media player is launched) used the defined graphics card custom gamma/color settings, the second instance always appeared to use the defaults which didn't look right on my screen.
