The CTX946 TV card doesn't detect a signal after cold boot, seems
the tuner FMD1216ME_MK3 suffers the same problem as FMD1216MEX_MK3,
as described in saa7134-cards.c (disabled IF, enabled DVB-T). The
card does work under MS Windows, after soft reboot into Linux it
continues to work, only then tda9887 is loaded as well.
I copied the relevant code from the BEHOLD_H6 section to MD7134.
