Lightroom RAW performing different from Camera RAW?

[canuck88]

I've been using lightroom to process my RAW files for the past few months, but the other day I decided to open a RAW file in CS3 (regular camera RAW) and noticed that camera RAW in CS3 processed it entirely different from Lightroom...

For example, when auto adjusting the results were extremely different...

Since both programs are using the same camera RAW, wouldn't/shouldn't the results be the same?

You should be able to get EXACTLY the same result, depending on which versions you're running.

Can you give us any more clues or examples?
