DPP 4 appears to work just fine with any jpg file. I have cr2 files from several (not listed) cameras. DPP 4 will only edit raw files from my 6D.
Makes sense. JPEGs are JPEGs, regardless of what camera or computer they are produced by, it is a single format so if the software can process a JPEG it will process any JPEG. RAW files, despite all being called .CR2 are different from camera to camera.
