How to multi-trim video without recompression: Sony Vegas Pro?

I already know there is and have tools that can trim video clips and also join video without recompressing but how come I can't do this simple task in Sony Vegas Pro v9 or AVS Video Editor v4? I also have Adobe After Effects but I'm still learning the basics. I can tell you that AVS does a more efficient job to do multi trims and recompresses in same standard while Sony wants to make the file 5 times bigger even manually adjusting all project properties to match exactly to input video. I like. I do however like using Sony Vegas because it can do more and the trimmer is much nicer. I read on avsforum.com this..

When you render video to any of the following formats, unedited video frames are passed through without recompression (smart rendering):

DV AVI

DV MXF

IMX MXF (IMX 24p MXF is not supported for no-recompress rendering)

HD MXF

MPEG-2 (for files such as those from HDV and DVD camcorders)

In order to perform rendering without recompression, the width, height, frame rate, field order, and bit rate of the source media, project settings, and rendering template must match. Frames that have effects, compositing, or transitions applied will be rendered.

..I spent a long time making the custom properties exactly to spec and followed what this person wrote and still would recompress and way larger. Can win for losing with Sony though. For ever thing it does easily there's another that's not. Can someone please give me detailed info on how to edit my movies with Sony Vegas without compression and also control the file size which by default should be the same bit rate if it doens't recompress, right? How do I do this one tiny thing that's mostly what I wanted Vegas for and can't control it. Thanks in advanced and if you know this answer then please be detailed as you can. :)
