Might be a driver issue. Which card ? It's an NVidia 8800GT. The thing works fine, XVideo works fine (as in, there's hardare scaling and what not). Even VSync works (since there are no torn frames). It's just that there's jitter, i.e. frames not timed well. Setting hires_tick smoothed it alot,

When watching videos in Solaris, I notice a lot of playback jitter. Under Linux, video playback is much smoother. Since XVideo in Solaris on NVidia supports vsync, I figured it might be a scheduling issue. This morning, I was looking into configuring a custom kernel for my Linux laptop, when I
