I do. I use a SG-2100 as well. I wrote my own little program by stealing
code from dvb-apps about 2 years ago.
I'm using the program for a FF 1.5 and a Skystar 2.6B: the drivers
support DiSEqC very well.

It's easy: you read the specs at eutelsat, and write your own small
program for "GOTO", and the other things you might need.

I did not supply the program to dvb-apps as I'm sharing code with
a modified (old) version of szap and some other code snippets from
dvb-apps: it's a big mess;-(

With vdr, you should be able to define the needed DiSEqC commands
very comfortably as well; I have not done this: I usually tell vdr
that I have a fixed dish, but do the stearing with my helper program,
if I have to (my dish usually needs manual fixing anyway, as it is
mounted not very solidly on a balcony: I'm not allowed to install a
solid dish here, and I have to readjust it after a move).

Either 'my' program or anything else is disturbing my SG-2100 every
now and then, though: it sometimes doesn't react on any command any more:
I have to remove the motor from power for about 10 seconds before it
reacts again.
