I haven't seen KIRO with DD5.1 on Shaw Direct, Rogers Cable or Bell Satellite for close to 20 years though it's difficult to tell with most consumer equipment below a mid range to high end A/V receiver. I saw it briefly switch to DD5.1 a couple of times but the signal became riddled with video and audio dropouts. It switched back to DD2.0 a day or two later. I've yet to determine if this is a station or Canadian feed issue. I suspect the feed used by most Canadian TV distributors is supplied by Shaw. If anyone can get it OTA it would be nice to know if the station itself has DD5.1 and from which repeater.
