[mythtv-users] Recovering when zap2it screws the pooch---a warning & some questions

[R. G. Newbury]

Sounds like you misunderstood things.

You need a separate zap2it lineup for each type of feed.
So it appears you want:
1)	An analog OTA (off the air) lineup;
2)	An analog channel cable lineup.
3)	An analog channel STB lineup.

These will likely have the same actual channels appearing at different 
numbers. So you saw your 2,4,5,7 moved to the 30's.

But it appears that you are not actually using an antenna for OTA: you 
mean the channels which are *available* OTA but which you actually get 
on cable. FORGET THEIR NUMBERS. THEY MEAN NOTHING NOW!

Go into zap2it and set up 2 distinct lineups. One will only have the 
cable channels you want to receive which you get *without* using the 
STB. The other lineup should consist of those channels which you can 
*only* get using the STB. Myth will know to tune the correct input, 
because the inputs are matched to the tuner/lineup combination,

I am not sure that you can include channels in both lineups where you 
can get the channel through BOTH tuner setups. It should work, but may 
not. The usual idea is that each lineup is distinct. You can have 
multiple tuners which receive and handle the same lineup but I am not so 
sure that you can have overlaps. Should work, may not.

No! The channel mappings to numbers are essentially arbitrary. Every 
cable co can and does use their own mapping. The non-cable-box channels 
are likely to be similar among local cable-cos but the STB mappings are 
often entirely different. You will have to learn to go by the call-signs.
