Problems with our video

After finally finishing our video, we were putting it onto you tube to be able to put it onto our blog and burn it on our disc. However we have had problems with this as it wouldn't upload onto you tube and when it did the timing appeared to have changed which made our video out of time and then made the process more time consuming to finish as we had to try and re-do this again. Another problem we have had has been trying to burn it onto the disc as the disc we originally bought said it wasn't blank when we tried to burn our video on to it. We overcame these issues by re-doing them and trying different things until we succeeded with this.
