Unfortunately, it doesn't work that way. The ATSC guide info is often
wrong if something unexpected happens (like a program running long).
It unfortunately is rarely more accurate than the SD guide.
You have to remember that the broadcaster is multiplexing this data
into the stream based on their database of guide info. It is not just
forwarding some info embedded by the content producer.
