It appears Cenamer Control (Central America) has been using 133.500 (in place of 123.900) in Sector 1 (High Altitude over Guatemala, Belize, Honduras, El Salvador). Any chance 133.500 could be added to the LiveATC feeds that cover this area ? The feeds at MHRO, MHLC, MHTG, MSLP. If it's at all possible having the Cenamer frequencies split from the local ones would be ideal as some of these Tower/Approach frequencies can be very busy at times.
