Is there something different in 9.1 transmission from other HD stations? On my system the colors are more saturated and the blacks are blacker. Altogether a great picture.
I know its 720P but so is 7.1.
I get it OTA. My DVR, a Sony DHG-HDD500, says signal quality good with a strength of 74 for 9.1 as opposed to 88 - 94 for 7.1 and most other stations. Everything goes through a Lumagen XS which has yet too be calibrated or tweaked to a Sony Ruby projector.
