Right, that is a problem, so I guess there must be some balance
between receiving timeouts on one hand and not receiving the full list
of channels on the other hand. Personally, I'd be slightly inclined
towards enabling users to get the full list of channels. I'd think
re-scanning is not something people are going to do too often, so
perhaps if it might potentially take a little longer, that could be a
price worth paying, in order to get the full list of channels?

Another potential good use for a complete list is when searching for
feeds. These transponders tend to be only used occasionally and I
doubt they will appear in NITs. So, I suspect that the only way of
detecting these channels will be to manually scan the transponder
list.

Given all that, these are just text files in some obscure corner of
the filesystem. My full list containing all the transponders from the
four satellites at 28.2E was only 4 Kb, so perhaps it might be
feasible to ship _two_ channel lists, where available? A minimal
starter file and, where available, a more complete list?

I'm not aware of any authoritative source of information. What I used
to produce my list was a combination of two internet sites,
http://www.lyngsat.com/ and http://en.kingofsat.net/ (another good one
is http://www.satcodx.com/ ), and then verifying those against the
satellite itself.

Cheers,
Marv
