Sometimes things just seem to be working backwards. My HR21-200 works best [speed wise] with 0x2AF. My HR20-700 works the same with either 0x2AF or 0x2CA. BUT: DirecTV keeps trying to push 0x2CA to my HR21-200, yet hasn't pushed it to my HR20-700, that's on the national release of 0x2AF. Both would work fine if only the HR20 had 0x2CA pushed and NOT my HR21.
