Hi Johan.<br>
<br>
This is 'similar' to my setup.<br>
I wrote a HowTo a while ago on getting a multi LNB DiSEqC switch to work<br>
<br>
Have a read
(<a class="moz-txt-link-freetext" href="http://www.mythtv.org/wiki/index.php/MultiLNB_Switch_Setup">http://www.mythtv.org/wiki/index.php/MultiLNB_Switch_Setup</a>). Compare
the "Port Layout" section on my page with the table in the PDF from the
site you linked to. If it doesn't fix your problems then feel free to
get back to me (either on or off list) and we'll step through the
settings and see whats up.<br>
<br>
My switch is DiSEqC 1.0 though and I havn't played with any 2.0 stuff
under MythTV. We'll give it a crack though =)<br>

<br>
Recently I decided I also wanted to watch some channels on Optus D2, so
did some research and decided to go for a Dual-LNB setup, which
apparently works with a standard sky dish (receive D1 and D2 without a
motor). See <a moz-do-not-send="true"
href="http://www.ultrapower.co.nz/dual_ku_band_lnbf.html">http://www.ultrapower.co.nz/dual_ku_band_lnbf.html</a>.
The guy sells them for $39 incl posting (Akl). It's a Zinwell multi
Universal Ku band LNBF using Diseqc for switching between LNB.<br>
<br>
So I've installed one, It works although I have quite poor reception on
D2 though.<br>
<br>
I have initially connected it to a FTA STB I had lying around as it
gives better signal strength info. So with that box I've confirmed my
dish is working.<br>
<br>
I have problems with getting it to work in MythTV though (I had it
working fine with my Standard sky dish LNB). In the Diseqc setup menu
of mythttv setup I've removed my exising LNB and added a "Switch", with
2 ports. Each of these ports having a "LNB" underneath them configured
to be "Universal (Europe)". The frequencies correspond with the one of
the LNB.<br>
<br>
When searching for channels I get no result though, none for D1 and
none for D2, I've tried multiple combnations (trying freeview
transponder frequencies on D2 and D1) just to check if somehow the
diseqc switching is not done properly.<br>
<br>
I took one step back and used "dvbtune" and "scan" with mixed result.
scan had no luck at all, but dvbtune does get a lock on freeview. I am
not sure which one is "lower level" though.<br>
<br>
Does someone have a similar setup working? I have the feeling it's the
Diseqc switching as I see quite a few reports on internet forums with
problems.<br>
<br>
See here my dvbtune output, any hints welcome.<br>
