If you are successfully editing native AVCHD video, could you please list your computer specs here? This will be very helpful for those of us thinking of buying or building a system. If you bought a pre-built PC you can just list the make & model. It might also be helpful to know what operating system and editing software you're using. For the purposes of this thread please only list your system if you are able to obtain smooth, jitter-free playback of native AVCHD video files while editing. Thanks!
