Where are you, and what system are you on? Can you find on line a listing of actual channel use (maybe not)? I'm a bit surprised that the system is still half analog. If you are injecting only two channels, I think they should not wipe out a bunch of digital channels unless:
1) you are attenuating the digital channels too much in the process of combining with your signals
or
2) your setup is injecting your signals at too high a level, overloading something, and splattering the added analog across multiple channels
(2b) your modulators are producing harmonics that coincide with digital signals at higher frequencies

EDIT: to test for case 1, keep the combiner in place, but turn off your modulators - see if you are still losing digital channels.
