I read in one Russian website, I think it is called relsat.org.
They recommend to create or modify "replace.list" in the var folder!
Anyone has experience with such list? It says that makes channel switching faster.
I don't know where you will place those files, but they are available on the forum
ignore.list, priority.list and replace.list are used to open the channel and zap them faster
