love this but...

The cpu usage reaches for about 96% which makes the video out-of-sync with the audio. But the playback is noticeable, from 25 to 50 FPS which makes it HD video. But the problem is that, video is moving slow when scenes that require a lot of resources from the CPU is being played, and the color changed by the way, it's bluish now. I hope you can help me with this. THank you.
