Sorry to spoil your theory, but those drivers are in the correct
directories. You'll just break it if you move them. The card has a few
chips that control different functions on its board (a tuner and a
demodulator, in this case). So the "saa7164" driver (which is in the
drivers/media/pci directory) pulls in those other two to support the other
chips. The "dvb-frontends" directory has nothing to do with MythTV or the
MythTV frontend. It's just the standard directory that media driver authors
install their demodulator drivers to.
