Well.. I don't really recommend using this one, it completely ignores almost all settings from VDR channels config and uses 
autopilot instead. Works for me, it's an ugly hack and i don't recommend it to be used. And it forces transponder bandwidth to 8MHz, 
as it's only one in use in Finland. I didn't want to make things more complicated (like to get settings from vdr ;)).
