I have what should be a reasonably fast PC: it's a Quadcore Intel 6600 at 2.4 GHz, 4GB of RAM, an ATI 3800 series video card and an LG L246WP monitor, which I selected particularly because it was supposed to work well with video and have no trails or other artifacts. So I should be able to play video with no problems.
And I can, as long as that video isn't Flash video. With Flash, what I see is tearing, especially during pans, and pausing -- every few seconds the video pauses for about 300ms while the sound stays continuous.
I tried going into the video card setup and changing vertical sync, pulldown detection, Windows Media video acceleration, deinterlacing and triple buffering. But no combination of settings I've tried has changed or corrected the problem in any way.
I've also tried enabling and disabling hardware acceleration in the Flash settings, to no avail.
This problem happens whether or not the video is streaming or has fully streamed in before playing. It exists in every browser I've tried. The problem also exists in at least some videos using VLC player.
So, what can I do? Is this just a Flash issue or is there a way to get it to work?
