Is there a recommended minimum distance that one is suppose to use on the M80 so it does not distort the picture on a 36" television? Right now I am at 2.5' without any problems and was wondering if I this is normal, or if maybe I have another problem. Also with my VP150 its quite odd, if I have the unit directly on top of the television, flush with the front edge I get distortion, moving it back a couple inches and all is well

Just curious,
