[mythtv-users] finetuning channels?

I've made a large list of frequencies of just 6 cities spread around the
country from only two cable companies and there are several duplicate
channel numbers in there. That's the reason why I never tried to include the
frequencies into MythTV because I have no idea how to handle those
duplicates.

Any chance The Hague was on the list ... And you still having it ? (VERY BIG
GRIN)
