Projection TV's

[Warlock]

Anyone got any experience with PS2 or Xbox on a projection TV. I just got a 52" widescreen and while its got a imput especially for a console the manual says that any accessory with fixed images for extended periods of time can cause them to be permanently imprinted on the picture tube. Of course the guy that sold me the TV said it was ok and he played games on a big screen all the time but what do you guys think?? Will it be safe as long as gameplay dont exceed a hour or so at a time or should i avoid playing games on it period . It clearly states in the warranty that damage from this is not covered.Anyone got any suggestions or tips??
