Raw Image Task, not DPP
1

Contrary to widespread belief, DPP isn't intended to deliver precisely the same image as the in-camera processing chip (Digic). That chip is special-purpose, highly parallelized, and much faster than home computers for interpreting sensor data into a JPEG image. Doesn't work worth a darn for spreadsheets or web browsing, though. DPP's goal is stated as "give easy-to-use high-speed RAW image processing with a PC."

Anyway, Canon used to provide software that precisely emulated the Digic chip: ZoomBrowser's Raw Image Task. Acknowledged by at least one Canon rep as "the slowest Raw converter on the planet," it ​does ​produce the same results as the Digic chip except for JPEG compression levels. Canon dropped Raw Image Task after ZoomBrowser 6.1 — released with the Rebel XS — probably because exactly emulating the processing of the Digic 4 would require hours.

If you have an old version of ZoomBrowser hanging around (maybe on the installation CD from your camera), you could give that a try. Or you could do like most folks, and ignore what the Digic chip would've done. Or shoot Raw+JPEG.
