Unless you have an AirTV dongle on the Wally in which case, as mentioned above, you can record 2 off Dish and watch 1 OTA, or 1 Dish and 2 OTA, or 1 of each or any combination of the 4 tuners. The one kicker is if you are recording back to back episodes off a single timer. Due to early start and late ending of a timer the 2nd tuner will kick in to start the next episode before the 1st tuner is finished with the current episode thereby tying up both tuners. Not a big issue but something to be aware of.
