Hi,
Having some strange Diseqc switching issues. Let me explain the situation/setup.
I have some setups with 4 dishes, Quattro LNB's, Venton MSG 17/16 or SAB 17/16 multiswitch and multiple TBS6985 tuner cards in a linux pc (Ubuntu 14.04, 3.19.0). Tuning works with Mumudvb,Dvblast or any other tuning program. All these setups where working just fine, now I got some new Venton and SAB multiswitches delivered. Using the same components together with the new delivered multiswitch(es), the diseqc always stays on SAT A, so if I try to tune to SAT B,C or D, I always get stuck on SAT A. If I just swap the new multiswitch with a multiswitch delivered some months ago it works. I tried several new multiswitches but all the same result, only SAT A.
If I connect a Dreambox or VU+ satellite receivere it works just fine. I also tried with some other PCIe tuner cards (&drivers) from another vendors and having the same issues. I already tried to contact the Vendors of the multiswitch(es) but they could not realy tell me what the difference is between the working and not working multiswitches (they look almost the same, just some new labels printed, probabbly just a new rev.)
Any ideas? Thx.
