I can see how the v20 is not working for your shots, and I agree that it's the camera and not you. I also have some types of shots/features that aren't as good as the g4 (over pixellation/compression, distance focusing.)
But there are also some fine features that other people are excited about. (I love the wide angle, sound, and manual focus.)
Unless other people are taking concert photos (your main use of the camera), they likely won't experience what you are experiencing... so they are just pointing out that ghery are getting good low light photos, the closest analogy they have to what you're doing.
You've posted your issue several times, and it seems like no one has a solution. The next time I'm at a concert with similar lighting (mid March) I'll try some photo options and see if I can come up with something for you.
