If I disable it via the 10 minute option in the notifications area of the taskbar, the video runs fine. Once the time is up, it goes back to stuttering. It's a windows xp installation, btw. Forgot to mention that. It doesn't slow down my computer at all which is good, it's just that I use youtube alot and that just happens to be what is messing up. I have the videos set to low res and speed too just to see if it makes a difference but no dice.
It's all of my audio. Not just youtube, as I had thought. Any video that I play anywhere at all stutters. The video picture is fine though. Reinstalled the operating system after my first post just because i had the time to do so and it remains the same.
All avast settings are left at default settings if that helps. Although did change the update timer to 480
