The only time I've seen clicks that weren't in channels is when something wacky was going on, like someone stole a page and wasn't smart enough to remove your AdSense, or people were loading pages via the Google translator, Google Cache, Yahoo Cache or translator ... you name it, lots of normal places it could happen, even via a proxy server.
Try this:
1. Go into AdSense Setup and click "Allowed Sites" and give AdSense a specific list of domains where your ads are allowed.
2. Double check your channels and make sure you have complete domain channels such as "mydomain.com" and then make sure your domains are properly canonicalized and in working order.
3. Put the meta "NOARCHIVE" in the top of every page you have control over just because I said so
See if that doesn't clear up the discrepancy and if it doesn't, ask AdSense to audit your account for any anomalies.
