The tuning at loading time really is more for getting an immediate
feedback that the driver works when developing, so it is set to some
channel we know we should get. We don't account for all possibilities.
Actually, there should not be any tuning before an application uses
the devices, but we left the staying-tuned-after-device-is-closed
option in for convenience. So it is quite possible that you won't get
a picture at startup, if your LNB or disqc settings are different.
