"Ever since an update of either Final Cut Pro, QuickTIme or Pro Apps (no-one really knows) Final Cut Pro has a nasty bug when exporting a self contained quicktime movie from a DVCPRO HD (720p & perhaps 1080i) timeline. The aspect ratio and frame size of the resulting self contained movie is incorrect and therefore requires render when brought back in a native DVCPRO HD sequence - even the same sequence the movie was exported from. For some of us, this is a big issue. Each re-render takes up to 2 hours per hour show."

Happy to report that this bug is now FIXED with the recent FCP update to version 6.0.2
