I have one Hr21-100 and two HR22s on a SWM8 module. All three receivers are on same port out of SWM8 and and all have Decas behind them with the ethernet cables attached to the receivers. The HR21 has the special 2 way splitter trick to power the DECA. The two HR22s can see each other but only one of the HR22s can see the HR21. So my issue i have is that that the HR21 is only sharing play list with one of the HR22s. Any one know why or has a solution to fix this?
