Hmm, I know of at least one tuner module for which the data sheet says that you must not use the I2C bus for at least 60 microseconds after programming the PLL, or the tuning will fail. Maybe there are other frontend components which are equally sensitive to I2C traffic right after being programmed? If so, that'd be a bug in the corresponding frontend module, which must include a delay call for the required minimum "silence" period on the I2C bus... IMHO, each module should ensure stable operation in itself. No sequence of calls to frontend functions should ever lead to reception problems. I'd say do not fix your calls, but rather identify the buggy frontend modules and fix those...
