Hi

I am very new to movie maker and I have just started a project to make a movie from my last holiday overseas but when I first started it by adding two files (of many) and editing them with fade in etc it seemed to save okay but when I added new files and editing and then went to save it again it looked like it was saving the whole thing all over again and seeing as I have a lot of files to add until I finish, this is going to take me ages, so my question would be how do I save the project on the run, can I just hit save and it will automatically save and update the original file.

Also when I have finished this project and I am ready to burn to disc what do I have to do to get it to burn and will it let me know how many discs I am supposed to use as I can imagine this will be very large by the time I have finished.

I am running Windows 7 Home Premium with Service Pack 1

Thanks
