get yourself a hack saw and turn it into a flat head screw.

make shure you have the correct bit usually a pz2 98%of the time make shure its a good bit tap with a hammer into the screw head then try removal this should work more often than not as you usualy have part of the flat on the back edge when the front is is comletly chewed up
most chewed up screws are caused by the wrong driver bit being used you know its the correct bit when the screw will stay on the bit whilst you carry it
you can also try a flat bit this sometimes works as a flat bit of differing widths will fit at different points into the "v"

Dear Big-all
Is your keybord missing a key??
Using the . once in a while would make your post more readable.
Although, some combinations would make fun reading

In this order :-
1. Impact driver (not much good if screw head totally knackered)
2. Hammer and small chisel, anti clockwise of course.
3. Last resort. Drill screw head off, remove whatever it's fixing, and remove shank with grips.
Forgot to mention easy-outs, which are left hand thread studs which you screw into the screw, if you see what I mean. These require a hole to be drilled into the problem screw head, so are only really useful on larger screws.

It often helps if you hit the screw driver into the screw(as said earlier) and then try tightening the screw up, before undoing it.
left handed drill (no its not a joke )
To avoid this problem in future learn to tell the difference between Philips and Pozi head screws. They're not the same but I've met mechanical engineers who don't seem to know this. The Philips head has tapered flutes whereas the pozi's are parallel sided. The Philips driver also has too sharp a point for the flat bottomed Pozi screw head. If you try it you will catch only the upper edges of the flutes and, if the screw is tight, chew them off. Having said that I once made myself a dual purpose driver by filing the point off a Philips. It worked most of the time!
As for getting this thing out, all the advice given so far is good though an impact driver is probably too big. I would go for the DIY impact driver. You hit the screwdriver with one hand while applying torque with the other and, as D and J have suggested, try changing directions too. I have one other trick that I don't think has been mentioned so far though it won't work on countersunk screws. File flats on either side of the head and use a spanner.
