Drop me a private email with the list of modules you have loaded with
analog tv and dvb-s is working. Maybe the ISL module is not being loaded
(which is required for diseqc). However, let's try to keep the thread
here public. It helps other people.
I tested the DVB-S stuff with an L-BAND modulator, meaning the 13/18v
output (or perhaps lack of in this case) was irrelevant. It sounds like
that could be an issue. I also have a small dish at home that I can test
Certainly, I have _not_ seen noise on the DVB-S transport unless it's
being introduced in the environment. I'll double check this also.
It's been a while since I modified the 3000 patches (and they were a
little rough around the edges). Time for more fixes I think.
