the active and passive scanners use the same mechanism, so that isn't
useonairguide on a channel is used to indicate if the EIT data should be
used for the channel. it is also set by the scanning if the signalling
tables indicate that there is EIT available for that channel
interesting that epgsnoop finds eit data. it indicates that the eit data
could well be present but just in a non standard place. we'll need to do
a bit of dvbsnooping to find out just where they might be.
Please join us in #mythtv on irc.freenode.net and we can go through it.
