Has anyone found a decent way to do basic editing on linux?

What I've found thus far:

For mpegs:


seems to work for doing the editing, but it dies on when when I try save.

MainActor demo chokes when I load a file.

Kino seems to only work on dv files.

glav doesn't support mpegs as far as I can tell.

for divx

glav opens the file, but then won't work with it.

Kino doesn't like the files either.

Anyone have anything up and working well??
