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.

Ok but how do other programmers cope with this problem. I have used lots of
other program's (under windows) and never experienced these problems before.

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

I installed knoppmyth R5A30 now. But diseqc is 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?
