Hmm, that's looks very much like the radio isn't working. To prove this
I hope you are able to build a new kernel. A single simple change is
needed in the source drivers/media/video/tuner-simple.c. Look for the
function default_set_radio_freq, then look for this piece of code:
buffer = 0x19;
Now replace '0x19' with '0x09'. That's it.
If running ivtv-radio -f 92.7 now is tuned properly, then this will mean
that I need to do more work to have the MK5 tuner work correctly.
