How to use skyscraper8 with a SAT>IP server:
The general commandline is as follows:

.\skyscraper8.exe satip IP_ADDRESS DISEQC POLARITY FREQUENCY SYSTEM SYMBOL_RATE

IP_ADDRESS is either the IP address (for example 172.20.20.122) of your SAT>IP server, or "auto" for autodetection of a SAT>IP server.

DISEQC is the DiSEqC 1.0 Port you want to use. Say "1" here for A/A, "2" for B/A, "3" for A/B, 4 for B/B

POLARITY is either "H" or "V"

FREQUENCY is the frequency you want to tune to in MHz. (for example 12226)

SYSTEM is either "S" or "S2"

SYMBOL_RATE is the symbol rate of the transponder you want to tune to in Ks. (for example 27500)

So a valid command would be for example ".\skyscraper8.exe satip 172.20.20.122 2 V 12226 S2 27500" to tune to the Hotbird DVB-NIP demo transponder, assuming Hotbird is at DiSEqC B/A.

If you don't know your SAT>IP server address, the following command would accomplish the same: ".\skyscraper8.exe satip auto 2 V 12226 S2 27500" 

If your SAT>IP server features a StiD135 chipset, you can also catch GS/GSE with it.
