It's not really a bug. It seems all DiSEqC equipment behaves differently.
I've had to fiddle with the diseqc code quite a bit in order to get my
configuration working properly.


To answer your question, that bit of code exists on SVN so it probably
exists in KnoppMyth as well.

Onderwerp: [mythtv-users] Diseqc Switching still not working?




I am running knoppmyth R5A26. I have a 4 way diseqc switch.

LNB1 is astra 19.2 LNB2 is astra 28.2 and LNB3 is hotbird 13.0.

If I run mythsetup I am not able to scan channels at LNB 2 & 3.

I tried with a Technotrend Budget and a KNC1 satellite card.

If I bypass the diseqc switch I am able to scan the channels.


I searched the user list and I found the following.

DVB, Diseqc and scan


At the end of this discusion Johan had found a solution.

Does this bug still exist in knoppmyth R5A26?
