lossless rendering

I have a DV camera. I've written somescripts that take the video clips from the camera and transcode them into flash and wmv files for my website.

Now I'd like to use kdenlive to edit and join clips. Is there any way to do lossless transcoding?

Forums:

If you are transcoding to flash and wmv you are already loosing quality.

If you pull your DV off the camcorder as a DV file with dvgrab, kino or kdenlive and then render it to DV raw is that not lossless?
