The only way to tell for sure is from the ivtv initialization log
messages, which you can retrieve with:
tac /var/log/messages |
sed -n '/=\ \ END INIT IVTV\ \ =/,/= START INIT IVTV =/p;
/= START INIT IVTV =/q' |
tac
However, from your modprobe.conf, I notice that you're not specifying a
tuner definition (i.e. options ivtv tuner=XXX), so it's likely you are
using the right one.
If you really want to see if it's a tuning issue, I'm going to be
posting a patch for SVN that fixes the frequency definitions so they're
"academically correct" in the thread
http://www.gossamer-threads.com/lists/mythtv/users/177694#177694 .
You're welcome to apply it to SVN, compile, and test. It shouldn't make
any difference (the tuner hardware's fine-tuning mechanism should be
able to "zero-in" on the channel, anyway), but it's possible that your
cable company is transmitting some channels at frequencies that are off
in the opposite direction that the tuner frequency list is off, so the
delta is too large for the fine-tuning mechanism on these channels.
