I am just wondering if it is normal to see some jumpiness in the preview pane when viewing a m2t clip? I find if I leave it at preview and half is ok but as soon as I go to good or best at half it really get jumpy. I would have thought my system is ok (q6600/880GT 512. Do you think it might be because it is on a 24".. ram is 4gb. Thanks for your help!
