Why it matters is that XP machines suffer what some call the DMA bug. The next link tells you it can affect playback.
...video (Youtube, etc) playback?
Getting slightly sluggish/ choppy video playback. I can't tell what the problem is. I ran speed & ping tests & all seemed fine there.
I *did* install (& the uninstall) the latest Adobe Flash. Now I'm back to 10.3...but it's still acting up.
What to do?
