91 is not very close to 119... How are you getting your az-el information? If the zip code calculator in the Dish receiver doesn't work, then you may have to use a more complicated program and enter in your lat-long.
You'll never find the sats you want just waving the dish around in different directions. You have to get close enough for the receiver (or a signal-strength meter) to get something. And for that, you need to be aligned fairly well, let's say plus/minus 2 deg in both azimuth and elevation.
