[mythtv-users] Zap2It - isn't this a two part problem?

I (Well, I and several other guys...) take care of KCTS-TV in Seattle, WA
and it was suggested by some friends that I stick my head in here and say
something. I am also a MythTV user.
All digital television stations are required by the FCC to transmit guide
data out 12 hours. At KCTS we transmit 10 days worth but the first 12 hours
are all that's required. Most major traffic systems at television stations
(And places like Discovery Networks and HBO and....) are capable of
outputting all sorts of sorted data. We output a comma delimited text file
from our traffic system that my PSIP generator grabs and parses out EIT's
and ETT's for our digital television station.
I'd be glad to answer whatever questions I can about the internal workings
of guide data generation at television stations or parsing it off the air
for the digital stations.

Do all stations provide *some* EIT data? If we could get generic
listings (without descriptions) from a large source (screen scraping,
stations directly, whatever) and then have EIT update those channels
24-48 hours ahead (depending on how much data the station actually
provides, maybe even just 2 hours...) then we would be relatively ok
since the EIT data would have the most accurate info to help deal with
conflicts, repeats, etc. The flaw in this is the expectation that
every station provides any EIT data, which I assume from subscribers
of cable, this isn't always available.
