Re: As bad as Amazon video on my TV
The FireTV stick and box show 0-4 mapped onto the direction and click keys on the remote and 5-9 if you press the 'option' button.
If you watch you get to know which half of the number space each number is in.
This massively reduces the search space - 5^4 rather than 10^4
That's still 625 codes given a 4 digit PIN
