I think this depends on how you have your house cabled.  I wired my house
with a central closet feeding each room with several RG6 runs.  My modulator
sits between the main cable feed and the splitter/amplifier.  The problem
occurs when your video sources are in different rooms and you use passive
splitters/combiners in you cabling setup in order to distribute the signal
to the rest of the house.  You create a loop that *could* push your modulated
channel down the main feed.
Here is an example:      ________________
                     ----|               |
                To   ----|  Splitter/    |
                TV's ----|  Amplifier    |_______________________________
                     ----|_______________|                               |
                                                              _________  |
                                                              |        | |
           _________                       |------------------|Combiner|--

                                             |              |

                                          |        |        |

This is definitely true for both ChannelVision and ChannelPlus modulators.
One interesting thing about ChannelPlus (and maybe ChannelVision too) is that
they sell a unit that can route IR along with your modulated signal.

The only problem I see with using a modulator for a mythtv box is your stuck
with only MTS/Stereo sound.  You would have to run a shielded line for any
other audio needs.
