Driver Update for BenQ 1620

Hi All! Just recently got a 1620 and so far I love it. I got the retail version and plan on flashing the firmware very soon. My question, however, relates to the driver availability link that’s posted on BenQ’s US site:

Driver Availability

There’s quite a bit of stuff in that 53 mb file! My problem is that I don’t know what any of it is or if I even need it; There is considerably more in that .zip file than just an updated driver. QVideo (what is that?) is in there and a bunch of other stuff. Can some of you experienced folks help me out? I would appreciate it.

Qvideo isnt really that useful unless you have a digital camera or work with DV files, its not needed for the drive at all.

Ok. The QVideo makes up the bulk of the contents of that .zip but there’s also something called DirectX81. All in all, I don’t think I’ll have any need for this stuff. Thanks.
