Try this:
Find the frequencies your cable company uses.
then use: test_ioctl --set-freq=tuner=<tuner>,freq=<freq>
Where freq is the frequency provided by your cablecompany and looks like
this: 175.25
Multiply that by 8(I believe), and set that frequency.

F.I.: test_ioctl --set-freq=tuner=0,freq=1402

Try watching again, it should work :)

Good luck,
