sorry, but i am not sure you can. If it is I've never seen it. I pretty sure you don't want to go to the store to find some pricey software when all you need to do is cut a short video. But there is hope. On some computers, mainly XP, there is a program called Windows Movie Maker. In there you can cut and edit and lots of other things to make it look really cool like fades from one scence to the next and make things look really old but I think all you need it to cut it. If its not on your computer you could try searching for some freeware (free) on the internet that could do that. Are you cutting it so that it wil fit as an attachment? If you are you could compress it or as some people say zip it. There is a drawback though. You might lose some quality and would be set a smaller esoultion so it might look tiny. But still you can uncompress it and it would look more normal.
Thanx

P.S. YOu might be qable to do it in Media Player 10, though I don't use it.
