HI ilinx, Yes... It can affect ANY workflow, if the capture settings do not match the sequence setting with regards to pull/up down. In other words it will affect a 24 or 25 fps sequence if the capture settings are set to 23.98 or 29.97 and it will affect a 23.98/29.97 sequence if the capture settings are set to 24 or 25fps. I've heard reports that this has changed in FCP 6.03, but I haven't had any opportunity to test that...
