I've been having problems getting rotor to work. The problem was crashing when rotor commands such as [E0 31 6B 13] are used in the diseqc.conf. other hex switch commands didn't cause a problem. I was told by another that this patch fixed this problem. But now it won't compile. I have been trying to get it to work with vdr-1.5.9 but I think the problem is because I am using amd64 linux which has been causing a lot of compile problems
