Hi Vaughn - you're going to hate me...

1) rename copies of the files you want to work with into the
alphabetic sequence you want.
2) burn & boot the elive CD - launch Cinelerra, cut and past the
kernel fix from the error box and relaunch Cinelerra.*
3) add the files to your project resources - one of the defaults is to
import a bunch of files and concatenates them into one big video/audio
project.
4) learn to navigate Cinelerra - working in the top row of the lower
left box**, place intron and outrons (not the real names) about the
bit you want to cut - hit delete button. If the next one isn't
adjacent, make sure you toggle off the inton/outron things. repeat
until you ... stuff you do in the main timeline will affect the video
& audio streams beneath it.
5) render the new piece with the same format as the resources - it is
an option and might just work.
6) log out & reboot into normal space - find fixed video.
7) Cinelerra often notes that Kino is good for capture/pre/post
maipulation. DIV is like default video format and pay attention to
video/audio sync - the way it is in edit isn't always how render
finishes your work. don't panic - render.

*ps Elive doesn't like you playing around as root - and there was
something about getting root.. try elive as the passwd.

I think you could finish your project after reading maybe 3 sections
of the Cinelerra CV documentation
**the bottom row of this box is also your friend  ;)  think interpolation
