[mythtv-users] DiSeq problems

I've run out of ideas on this one. My setup: tuner card connected to 
DiSeq 2.0 switch, with the Diseq switch connected to two satelites, each 
connected with 4 LNB to the switch (its a 9/16 switch, which supports 2 
SAT, and internally generates the tones needed to keep each LNB fixed).

The STB i have connected in parrallel (setup: DiSeq 1.0 switch with 2 
LNB) works without problem and receives both Astra 19.2 and Astra 28.2 
without problem.

I'm running MythTv 0.20-fixes (on my test system the latest SVN) and am 
noting that after installing the diseq switch i cannot tune anymore to 
the channels. I've deleted the DVB tuner and re-installed it. The DVB-S 
setting now tells the system its connected to a 2-port switch, and the 
switch it connected to 2 LNB's (universal LNB, tone and voltage). 
Mythtv-setup seems able to scan astra 19.2, but not able to tune most of 
astra 28.2. And even this is not always working, as can be seen in the 
attached log.

Attached a log from mythtv-setup, and from mythbackend trying to tune 
(this from operational system, temporarily re-configured to support 
DiSeq switch in order to test difference between budget and full feature 
card -> same behaviour).

Anyone have an idea how to solve this?
