Software for xVid/AVI editing

I have several AVI(xvid) videos. I’d like to add some text titles in each video, trim some part of the video, insert intro clips without reencoding/rendering the whole video again. What software should I use. It should be simple to use and fast. I don’t intend to convert the format. I just want to add some text titles in the existing avi file

That’s the hard part…:wink:
But take a look @ VirtualDub and it’s plugins…
