Here’s the scenario: Your guide is working fine. You’ve got one of the custom Australian options implemented, and everything is great.
One day, you notice there aren’t any scheduled recordings coming up. Or, you hit the Guide, to be confronted with two and a half channels of “No Data Available” entries – or worse, it’s all gone missing.
If you’re using one of the free options – and the actual download process for your guide provider doesn’t seem to have a problem – chances are this is because your data source has had its channel name changed.
To fix, hop, skip and/or jump into Settings, TV, Guide, Add Listings To Channel. If the channel names available are different from the set attached to your channels, you’ll need to go through each channel and re-associate them.
This happened to me a couple of times with EPGRunner; I expect IceGuide/IceTV to be much better (as their data source is semi-smart, eg, possibly humans).
