My parents now watch the local ctv (aka Kitchener CKCO) in SD instead of the Toronto CTV-HD for The View due to problems like this. So its not the first time something like that has happened.
Tonight's Daily Show did the same thing. Only they cut to Nightline oddly enough for a couple minutes at the start and then joined the Daily Show in progress so it's just not simsubs they can't seem to get right.Go OTA and watch the ABC feed from WKBW, and you won't see problems like this happen.
