you are right, I had to guess your hardware setup.
Your setup is working, but I like the explicit approach because it is
more obvious what is going on.
In your case I had done it the following way:


some ASCII art:                -----------
                              |Switch 1   |
                              |E0 10 38 F0|---ZF 1 (e.g. 19,2E low vert.)
               -----------    |E0 10 38 F1|---ZF 2 (e.g. 19,2E high vert.)
              |Relay      |   |E0 10 38 F2|---ZF 3 (e.g. 19,2E low hor.)
DVB-CARD  ----|E0 10 38 F0|---|E0 10 38 F3|---ZF 4 (e.g. 19,2E high hor.)
              |           |    -----------
              |           |    -----------
              |E0 10 38 F8|---|Switch 2   |
               -----------    |E0 10 38 F0|---ZF 1 (e.g. 21,5E low vert.)
                              |E0 10 38 F1|---ZF 2 (e.g. 21,5E high vert.)
                              |E0 10 38 F2|---ZF 3 (e.g. 21,5E low hor.)
                              |E0 10 38 F3|---ZF 4 (e.g. 21,5E high hor.)
                               -----------

S19.2E  11700 V  9750  v [E0 10 38 F0] W100 [E0 10 38 F0]
S19.2E  99999 V 10600  v [E0 10 38 F0] W100 [E0 10 38 F1]
S19.2E  11700 H  9750  v [E0 10 38 F0] W100 [E0 10 38 F2]
S19.2E  99999 H 10600  v [E0 10 38 F0] W100 [E0 10 38 F3]

S21.5E  11700 V  9750  v [E0 10 38 F8] W100 [E0 10 38 F0]
S21.5E  99999 V 10600  v [E0 10 38 F8] W100 [E0 10 38 F1]
S21.5E  11700 H  9750  v [E0 10 38 F8] W100 [E0 10 38 F2]
S21.5E  99999 H 10600  v [E0 10 38 F8] W100 [E0 10 38 F3]

Maybe this posting can help someone to understand the "magic" of DiSEqC.

OK, now we have pinpointed the DiSEqC weakness of 1.3 cards lets hope it
is possible to find a solution.
