Guide data:
With your current setup you will only get guide data if you are tuned to a 99 or 101 station. That's because of DirecTV's signal stack plan. There isn't enough bandwidth for the signals from all the satellites to be seen by the receiver at the same time, so DirecTV stacks the 99/101 signals together, and the 103/110/119 signals together. At any one time, the receiver is only seeing one set of signals, either the 99/101 or the 103/110/119. Great idea at the time, but what to do about guide data? If the guide data was only on 101, a receiver tuned to a 103/110/119 channel would not see guide data. So DirecTV decided to put the guide data on 101 AND 119, so regardless of what satellite the receiver was tuned to, it would also receive guide data.
Now along came the Slimline 3. That does not receive 119, so how to solve the guide data problem when you tune to a 103 channel? They could not change the signal stack plan, because that would mean modifying all the receivers already out there. So they came up with a clever idea, they faked the 119 guide data by putting the 101 data onto the 103 signals. That was done inside the LNB. So the receiver when it is on a 103 channel thinks it is still getting guide data from 119.
And the SWM LNB is no help. You need an SWM8 multiswitch, with the 29v power inserter.
But you don't have the Slimline 3 LNB, you have separate LNBs. This means when you are tuned to a 103 channel, there is no guide data. You solve this by going to the SWM switch. SWM carries the guide data over a separate guide data channel between the SWM switch and the receivers, and the SWM switch always takes the guide data from 101, it does not matter what channel you are tuned to.
Using the SWM switch won't change the signal levels you are getting from any of the satellites, they will be just the same. But it will make sure that any guide data updates you are getting from 101 are there even when you are watching a 103 channel.
