I have commented on my unwillingness to do this right now, because full EPG
isn't finished yet. The concept of using now/next to alter the program times
is fine, but I am not to that stage yet.. I do not want to use the now/next
data with what code is in .17 because it can't really be used for scheduling
and I don't want to give people a false sense of security when they hit the i
key in frontend and see guide data..

The previous one I rejected because you cannot schedule from it.. The data in
0x4E and 0x4F is duplicated in the 0x50 tables, so there is no point in using
0x4E / 0x4F until later on IF its used to alter the other guide out there..

Have you looked at any of the posts regarding EIT collection plans? Currently
it hangs off of tv_rec and always re-captures data when you tune to a
multiplex.. I have not gotten guide inserting correct for everyone, and until
that is achieved I see no point in schedulign collection. EIT collection
should also be driven based on how much data is present not a fixed number..
