Soi got my new CPU and i was like OMFG! i have always wanted Windows Movie MAker and i played with it but i don’t know how to change the rvmb. files to a different format...Can anyone help me?

wow! this is still here? Oh well i figured it out so nvm....

I thought I was downloading my movie from dv tape to Movie Maker 2 but I finally had to cancel the 'capture' process after waiting a few hours & the folder was blank.
It was suggested I use a high speed data cable. Could this be a solution?

i’m trying to make a music video for my class, but when i try to import audio files from iTunes it doesnt recognize the files, and they arent even there to try to import. help please!!

I tried to retrieve the movie I was working on and I got a pop-up that says that another user is on my computer with windows movie maker and to get rid of that window before I start my window movie maker, there has never been anyone elese using my computer, so I don’t know how to shut down “another users” , can you hep?
