Warning! This post is by a rank amateur on the video side of things. Be kind.
I have a PC in the entertainment center that functions as a MC client. I recently "upgraded" that PC from Windows 7 to Windows 10.
The PC has a circa 2010 Intel integrated graphics, which worked quite well under Windows 7.
However, after the upgrade to Windows 10, I noticed some, let's call it, jerkiness in video playback of DVD-quality and 1080i-quality video streams.
Poking around I discovered that Intel supplied drivers for that video hardware for Windows 7, but did not do the same for Windows 10. So I was running on default Windows 10 video code. That was less than optimum (understatement).
Long story short (probably too late for that...) I purchased a Zotac video card (with a Nvidia GT 710 GPU) becase it would work in the ~ancient~ PCIe x1 bus in the PC.
Longer story shorter...
The default driver that Windows 10 downloads for the card works better than the driver than came on the Zotac CD that came with the card, or the latest driver that i downloaded from the NVidia site.
YMMV and all that.
Bottom line ---
MC is showing video quite well once again.
