Sell it. Buy another brand of camera or something that will make you happy.
Thats probably the short answer. Much like the banding issues I'm trying to see if any other GH2 owners are having the same concerns. Do they feel the GH2 is an improvement in quality over the GH13. I have filmed several productions with the 7d and T2i and always had an eye on the GH1 and jumped on it once it was improved with the hack, I will not go back to the problems one can have with Canons. I will still be happy with using my GH1 for now, but was really looking forward to all the GH2 had to offer.
