I am also experiencing what seems to be problems with diseqc switching. I
think maybe mythtv will neglect sending a diseqc signal even when such
signal is needed to tune the switch to the right lnb. I'm wondering if
anybody can tell us the logic behind the diseqc switching code. Will a
diseqc signal be sent whenever one tries to tune to a channel? If not, when
will mythtv choose not to send a diseqc switch signal?
