Thanks for joining the NUC community.
Try updating to the latest video drivers and BIOS:
File name: WYLPT10H.86A.0030.EB.EXE
Thanks so much for the answer Alan. But everything is updated to the latest.
reinstalled windows 8 and done all the updates
installed all the latest intel drivers (except chipset and infrared that for some reason wont install)
installed the latest silverlight and the latest flash player.
tested youtube and netflix on both firefox, ie and chrome.
tested netlix on the netflix app.
All this is tested on a panasonic viera p55st50 (plasma tv) running on 50hz
besides the weird driver problem all youtube and netflix videos are stuttering.
I have attached my dxdiag outputfile.

Thanks for the detailed information. I have escalated similar issue back in April and our engineering team is working to get this problem solved.
The install issue is something with their drivers and possibly their new driver detect app you have to use. I have the same issue on a d54250wyk with the (very old and seemingly out of date) chipset and IR driver ('latest' version 220.127.116.117 and 2.9.1007 respectively). Of course both continue to show as being installed fine in the device manager. It also didn't list the latest video driver which was available via Windows Update.
Net is: It isn't you, it's them.
