[mythtv-users] Update on air guide.

[Gareth Glaccum]

Somats gone screwy.

I have the master backend running 3 DVB-T devices, channel input/source is 
called DVB or something.
I have the slave backend running 1 DVB-S device, channel input/source is 
called satellite

Both sources are set to use on-air-guide only.
However, nothing is being updated for my DVB-S, all the channels now read NO 
DATA

Can I force an update from on-air?
Any ideas why the scheduled update is not occuring?
