If you're in Atlanic Canada there are no rules. It could be very quick (rare), several days to a couple of weeks (typical), never (sometimes), it could show up in SD not HD and even sometimes two of the same episode in SD and none in HD. My understanding is the person in charge of this in Ontario actually gets them up fast. In Atlantic it could not be worse.
I'm NOT a Rogers employee; I was a satisfied customer, but not anymore.
