Hi Matthias,

thank you for writing this patch and looking at my issues.
I have a similar splitter and the two reciever connectors are looking 
symmetrically, so I don't see through which one the DiSEqC sequences could be 
blocked. This should also be printed on the line-splitter. Has anyone here on 
the list some confirmed information on this issue, how such a line splitter 

And another question to the list: Anyone using this patch with more than two 
LNBs? Does it work for you?

Since I have some other issues with my SS2 card I have deactivated it for now.
If you work again on the DiSEqC handling and think I should test it, please 
just write an E-Mail, I can reactivate my SS2 card than.
