Weirdness on WCVB (at least for some Canadian viewers)

Davros2006

Lately, whenever I'm viewing WCVB on cable here in Canada, the following happens...

I see an ad for the Slap Chop, but I hear the audio for something completely different at the same time. To make matters worse, the ad originates in Canada (due to a Canadian web address shown on screen) but the sound is definitely from WCVB, meaning I can't see what's being heard until the 2-minute ad is over, and then things return to normal. (This strange happening also occurs with other 2-minute ads with Canadian web addresses that cover up the WCVB ads and promos but the audio does not match at all.)

It should also be noted that at least two or three of the incidents I've noticed happened during breaks while the Ellen DeGeneres Show is on.
 
I could understand if the system were sim-subbing the program, but if not, I'd contact the CRTC - someone's not playing right, and it appears to be the cable system...
 
I thought CRTC rules mandate that the entire programming gets simsubbed, not the commercials? In other words, the program is not simsubbed, but the ads are? Is that against CRTC rules?

Typically switching of video feeds is done by a device known as a "audio/video router". The router in normal mode has "audio follow video" or "breakaway" modes. It is very possible the router controller has glitched and is telling the router to only switch the video level but to ignore the audio level.
So you get different audio and video because of this.
