Falcon,
I have a Hauppauge 950 (not sure about the Q at the end).
I'm running Windows 10 Home on an Acer Aspire V5 573p-6896 Laptop
This Laptop has an Intel i5 Processor at 1.6GHz - 2.3GHz
It also has a Crucial 256gb mSATA SSD for the OS and Office Package, it then had a 500gb Western Digital 7200rpm Hard Drive for Programs and Storage!
Finally I have 12gb of G.Skill DDR3L 1600 (PC3L 12800) Laptop M

I only have the Hauppauge 950 hooked up to the HD Antenna that came with the Tuner.
I have WinTV v7 installed on this Laptop and yes, I do notice some flickering when moving the Window.
I'm not sure if the Software is Up to Date or not, I believe it installed a newer version than the one I had when I installed it on this computer with a fresh copy of Windows 10.
The Flickering is minor and only happens while moving the window, to me it's no big deal!
If I remember right I had problems with the Flickering with Windows 8 & 8.1 installed on this computer (it never had Windows 7 installed on it).

I do have a Hauppauge HVR-1600 Tuner on my Desktop Computer, it has Cable Hooked up to it.
This computer also has Windows 10, but it's the Professional Version.
Not sure of the version of WinTV that is on this computer.
This computer is an AMD Phenom II x4 940 Quad Core at @3.0GHz
There is 1 x 500gb Hard Drive for the OS and Programs & 2 x 1TB Hard Drives for Storage (all Seagate 7200rpm)
I only have 8gb of G.Skill DDR2 1066 PC2 8500* 5-5-5-15

I'm not sure if this Flickers when moving the window or not?
Haven't really used this computer in a while.
