easymama, here's how I do it maybe this will help.
import the whole clip into Windows Movie Maker, then drag it down into the timeline. The '+' will magnify the timeline so you can work in 2 second increments. When you find where you want to start or end your clip, put your cursor on the beginning or end of the timeline. When you hit the right spot the cursor will turn into a double arrow. Drag the double arrow to where you want to start or end the clip & it will trim it to that point. You may have to play with the magnification "+/-" so you can trim the clip exactly to where you want it to be. I also use the time counter in the display to note where I want to trim to. I usually trim a 30 second clip roughly, then zoom in to trim it to 22 or so seconds for example.
Once it's trimmed to the length you want it, click file > save movie as. This will let you save it to wherever you want. The next step will give you settings that let you compress it, and it will be saved as a .wmv file.
Once you get the hang of it, you'll get pretty quick at cutting up larger clips. Personally, I prefer to work with entire movies & chop them down, the flow is easier, but I also use it to trim 30 sec clips down to 20 etc.
If you need any help, just let me know, I can get on icq and give you a hand if you need it
