Unexpected HiDPI in MoviePlayer

I am using movie player with .mov files on Mac and .wmv versions on windows. The .movs do fine on Mac and the wmvs do fine on windows running within VMware fusion. On a surface machine, however, they come up half size high resolution surrounded by black. When I just double-click on the wmv file itself on the surface box, it comes up full size. Is this a known behavior?
