I play multiple instruments and i would like to make a cover video of me playing all of the instruments, in one video. I've seen a lot of other videos where its done,but i'm not sure how to do it in windows live movie maker or if it is even possible in windows live movie maker. I think it can be done but I just have no idea how. Please give specific instructions on how or a different program where i can do that.

I just attempted to purchase your product online but it hangs up at the very end.  Can you assist me in completing the purchase or can you find my in process purchase and assist in completing it?

I have got a lot of videos on my computer, in mov, mp4 and avi formats. Can I use a single video or DVD burner to burn all those files onto my blank dvd disks? I tried nero burner, not good. So I hope I could get an answer here and can you tell me how? I prefer an easy way to do this. Thank you very much!!!
