Hi guys hope someone can help me...i recently downloaded comodo antivirus software and it had a compatibility issue with windows 10 and to cut a long story short I started a fresh and reinstalled windows 10. I obviously lost all my apps so reinstalled those two including vlc player. I use my 4K TV as the monitor and have run the pc like this for 8 months with no problems at all downloading and watching movies. Now the play back is choppy on VLC and windows media player...i have tried updating video card drivers and reinstalling VLC and nothing has worked...it would seem the updates have caused the problem and stupidly I didn't create a restore point...anyone else having issues or have and know a fix?
