 Daniel, I've seen that you haven't applied similar code in #437.

 Don't using a dvb card marked as open on demand for active eit scan seems
 more logical than using it all the time.

 I started again on making the eit scanner global. So we will be soon able
 to scan only occasionally. But it will take one or two weeks till it is
 finished.

 Due to a hardware or driver bug in the dual tuner card Hauppauge Nova-T
 500 there is some demand to disable the active eit scan for one frontend
 of this card. Some reports suggest that a specific pattern of tuning
 commands can cause a usb disconnect. The disconnect is a nasty error since
 neither the dvb subsystem nor mythtv are hotplugable. The backend is a
 zombie after a disconnect and the kernel needs a reboot.

 We had also occasionally request to make dvb_on_demand useable with
 activated EIT.

 I don't think there is a great need to apply this patch now. But I added a
 database update which disables dvb_on_demad for each card wconnected to a
 useeit videosource.
