 Replying to [ticket:3529 anonymous]:
 > Fails to switch satellites on a channel change. This problem affects
 both live tv and scheduled recordings. Pressing "C" to toggle inputs
 successfully switches satellites. Channel scans also work fine.
 >
 > Problem is worse in branch 0.20 as scans don't work either. In 0.20
 satellite stays stuck at the first "input" created in "Input Connections".
 The only way to scan the other satellite is to delete and recreate the
 card and create the other input first.

 I can confirm this bug. Its a show-stopper here in Europe, where its quite
 common to have multiple LNBs connected to DiSEqC switches. Here's a log of
 what happens on the backend when switching channels from 1 satellite
 (Hotbird 13E, Port 1) to another (Astra 19.2E, Port 2):
