Just got a new system of Axioms (all very nice) but have a shielding problem with the VP150. It's sitting on top of my 27'' Toshiba (regular TV, 5 years old) and it's effecting the picture.

Is there any material (thin!) I can put underneath to stop it warping the picture? Right now I can put phone books underneath (gives me the distance from the TV I need) but it doesn't look good and my center is getting higher than I would like.
