I'm not really into Windows but I had a client who needed a 5.1 surround .wmv file created and the only cheap solution I could find was Sony Vegas since Final Cut Pro does not do surround sound. I had Windows XP installed under Bootcamp on my Mac Pro and installed Sony Vegas. Just for the hell of it I installed the Aja Xena Drivers and my Kona3 showed up. I was able to view HD video under Windows on my mac using the Kona3 Card. Pretty weird what you can do.
