I've had a Olevia 242T for over a year and love it but to my knowledge there ain't NO code or scan to operate it with a Dish remote (and most, if not all cable remotes). Evidently Olevia uses some oddball frequency for its remotes, I'd have bought another one if it weren't for this. My sister has a 37" and same problem, dunno what Olevia those codes from Dish might work on but they don't work on mine or hers, neither does scanning.My solution was to get a Sony VL-600 learning remote from Walmart for $25. Works great and easy to program and use. Keep in mind that its IR so the TV has to be in the same room as the receiver. Good luck.
