Sorry, IIRC is a geeky/loser abbreviation for If I Recall Correctly.
For more information on cable TV frequencies, have a look here:
I just had a look in frequencies.c here :
for the channel maps, and the US cable HRC maps are WRONG for channel 95-99.
If you look in the lists, each one has an extra 0 on the end. For example:
channel 95 is listed at 900,000 where it should be 90,000. This is probably
causing your problem. Is you cable system really us-cable-hrc? If not, try
switching to regular old us-cable. Otherwize, your best bet may be to
download the source, edit frequencies.c and compile your own.
Any developers on this list care to fix this before the next release?
