I am having issue with playing videos on my laptop. I posted about this before, but I am still stumped. Videos that I watch on my other PC's and which are fine are awful on my laptop. There is a green bar running horizontally about 1/2 along the top of the screen and the colors "run" in the videos. I downloaded the latest K-Lite pack of codecs, but to no avail. I know I didn't used to have this issue with this laptop (fairly new Samsung running Windows 7) and I can't imagine what might have changed the situation, but I would really entertain any suggestions to fix the issue.
