Got a couple of questions about movie maker, hopefully someone here might know the answers.

1) One of my clips I need to trim about 4-5 frames from the end, but I can't move the scrollbar accurately enough to remove less than 0.2 of a second... Any ideas?

2) I want to take one of my clips and split the audio and video.

At the moment i have
(clip: with audio + video)

and i need to get
(clip: with audio + fade-to-black video)
(clip: no audio + video)

If anyone knows how to do that with Movie Maker, please let me know! And if it's not possible on MM, what program can I use to achieve this?
