<VV> wheel rusted to hub

[babacher]

OK, I'm still a newbie... continue being gentle with me.
 
I have a flat I need to get fixed, but I can't get the wheel off the hub!


I've asked friends and they say they have seen this problem, and they made
suggestions (which didn't work).  I've never seen it before.  The repeated
suggestion I got most was to remove the lug nuts, then lower the jack until
the that tire rests on the ground - and the weight of the car on that wheel
will pop it free.  I did that a few minutes ago; it didn't work. 

What do you guys/gals suggest?
