I thought it would be time to finally update outdated sources.conf. Patch is 
against sources.conf delivered with VDR 2.1.3.

Some things came up, and I would like to hear some opinions about them.

There was/is entries like:

S28.2E for Astra 2 satellites and
S28.5E for Eutelsat satellite at almost same orbital position

Both satellites are supposed to be watched with one dish and LNB, but still 
they have their own entries in sources.conf.

Similar example is "S1W Thor 5/6 & Intelsat 10-02". Thor satellites are 
positioned 0.2 degrees apart from Intelsat.

So should these satellites nearby eachother to be combined as one, or should 
every one to be separated as its own position?

If these are officially two separate positions, they should be contained as such
in sources.conf.
I have encountered the same problem while implementing the DiSEqC configuration
dialog. My approach will be to make cDiseqcs::Get() search for a suitable
DiSEqC entry with a certain tolerance. A value of +/-0.3 degrees would cover
the cases you mentioned. Or should it be even +/-0.5?

This is why I wanted to join them together, so if such change will be made, 
separate close to eachother positions don't really matter. I think
0.5 degrees might be too much apart (depends of configuration.. dish size specially) 
and rare condition, and making VDR to steer dish "in
between" two would make too much complicity, right?

This "tolerance" would mainly apply to setups that have a fixed dish pointing to
a position at which there are two satellites close together. In my upcoming 
configuration dialog it will be only possible to specify *one* sat position per
LNB, so the tolerance will allow receiving both positions in such cases. Whether
the dish is actually directed to either one of the satellites, or "in between",
is up to the user, depending on which position his preferred.

If you have a motor dish it will always be positioned exactly to the
requested angle, so there's no need to go "in between". And that's also a reason
why sources.conf should contain separate values in such cases.

Thanks for the revised patch (v3).
