Can anyone with an AVR with this chip (harman/kardon 254/354, emotiva) comment on upscaling quality/amount of cropping of the 2x/3x zoom modes? I'm looking to upscale a 480i letterboxed source (ie laserdisc movie) to 1080i and fill the screen widthwise with the zoom so my 16:9 display does not show the film 'windowboxed.' TIA.
