Tim,

Obviously I don't know as much about PSIP as you. You mentioned you are 
involved with PSIP being transmitted OTA (is that Over the Air?). From 
that should I conclude that we would or would not be able to get Cable 
and Satellite schedules using PSIP? You said you transmit data out ten 
days. What is the source of your data? I'm guessing you're using the 
program director's data to create your PSIP data. Is that correct?

At the present time the way Mythfilldatabase works, it can grab data 
from multiple sources, but there is no assumption of one source being 
more accurate or complete than another so, for example, if I were to 
download the schedule from datadirect then download PSIP (which it can't 
currently decode) the second set of data would replace any channels 
already downloaded from datadirect. However, this is dependent on the 
order they are downloaded. I'd have to look to see if the order of 
downloading can be specified by the user. I think it might have to do 
with the order the sources are added in MythSetup.



Carl.
