quick look at some literature shows increasing the caps value lowers the freq output of the resonator, so changing resonator/crystal without changing caps will probably give higher frequency, also might explain the high pitched noise of some controllers, seems resonators are piezoelectric ( convert vibrational energy into electrical), so the things are vibrating at very high frequencies ( sorry guys I thought was interesting stuff, all new to me). Also seems going over 30mhz some other issues come up with resonate frequencies.
