This is most likely completely unrelated to your issues with X.  This is
a problem with your tuner card or its drivers.

If you compiled a new kernel did you remember to re-compile any
out-of-tree kernel modules?  Are you sure the tuner drivers have the
correct (versions of) firmware to load?  Did you check dmesg?
