Hi All 

I have been putting together a windows movie maker project and recently "saved movie for computer" and burnt a disc.. brilliant! 
A few days later i needed to make some amendments, so i moved a few pictures around and tried to do the same thing... however i now get the error: 
"There are missing or unusable files in your movie maker project that are preventing your movie from being saved. please check that file preparation is enabled in options, or remove the files and try again" 
And then there is 1 or 2 pictures missing (out of circa 800).. but they arent missing from my file.. movie maker for some reason removes them... and it isnt the same picture each time! 

I appreciate there are similar posts on the forum, however i've not seen a suitable fix to this in the responses?

One bit of advice was to split the pictures into 2 lots and then burn as one DVD, might this work? how do i do this?

Would really appreciate some advice. 

Many Thanks!
