Uncompressed avi to divx/xvid.
 

Here's the deal: as a happy user of CCCP I don't have any coded related software installed, still I need to compress avi file from digital camera into divx or xvid (doesn't matter) but without installing anything that will destroy this wonderfull codec harmony. Do you guys know perhaps of some endoding programs that contains its own encoding codecs so I wouldn't have to install anything additional?

You can safely install the XviD codec over the top of CCCP without disrupting anything. If you do so, then VirtualDub will be your ally in this particular endeavour. I don't know anything that will do it without an installed codec though.
