I finally got it working but I dont understand why. I have had
the following problem for several days which I couldn't fix.
I started playing with ptune-ui.pl and changed "NTSC" --> "NTSC-hrc".
It worked after that
NTSC-HRC is just another frequency table. Most cable systems use
CATV STD, but since that would be too easy, they came up with a bunch of
alternative ways to assign channel numbers too. HRC stands for
Harmonically Related Carrier, which means that the video carrier is
assigned on a nice "round" 6MHz interval. There's also IRC (errr
Incremently Related Carrier I believe), which is the same as STD except
in the A and T channels. In IRC, the lower edge of the channel is on a
6MHz interval, and the video carrier is 1.25MHz up from there.
Anyway, long boring technical stuff aside, I hear some cable
companies use HRC. There's nothing wrong with you for having to use it :)
