Thanks Chris & Michael,

I don't think I'm suffering from the 11 vs 14 day problem you  
describe -- although I've hardly ever had a full set of EPG data, so  
I may be having that problem too and just haven't seen noticed it yet.

The threshold that you both mention seems like the culprit to me. I  
checked my current listings and I have 35 channels reporting "no  
data" and 26 with data. So, even though there are a lot of missing  
channels, I guess that it is returning a high number of programs for  
after 6pm, so the listing isn't updated.

Unfortunately, I'm not compiling from source. So I don't think I can  
fix this easily. I guess I'll just keep flushing my database and  
restore every few weeks when it starts bothering me again. Perhaps  
Michael's change should be merged into the release in an effort to  
improve this area? It seems to me that the threshold is set  
unnecessarily high currently.

Thanks again and regards,
