Actually, I think I solved this. I think the tuner I'd selected must have
been locked by something. When I selected a different tuner it did a full
channel scan properly.

However, it didn't actually find the new channel so that's another mystery.
Any ideas why it wouldn't find the new channel that my TV effortlessly
added to its line up after a channel scan 20 minutes earlier?

What I want to do is leave the existing channel definitions untouched and
have the scan just add the new channel. I don't want to lose my existing
channel definitions and have to type that all in again. But at the end of
the scan these messages come up and I've never understood what they all
mean. Can anyone please describe what these messages mean at the end of the

- "Found 40 new conflicting DVB channels". If they're new what are they
conflicting with?
- "Found 30 conflicting old DVB channels". What is the difference between
these "old" channels and the "new" ones in the previous message?
