[mythtv-users] Re: DVB, Diseqc and scan

[Johan Tufberg]

Hi all

I've fixed my problem thx to Arne Varholm. I found some old postings on 
the dev mailing list about the issue I'm facing so i contacted one of 
the fellows in the discussion and Arne told me that I could comment out 
the following lines in dvbdiseqc.cpp

 if (ioctl(fd_frontend, FE_DISEQC_SEND_BURST, SEC_MINI_A ) == -1)
 {
     ERRNO("FE_DISEQC_SEND_BURST failed");
     return false;
 }

Now it works like a charm. My C++ skills ar very basic and I do not know 
how to file a bug report (if this is a bug) so that it can be 
implemented in the source distribution. The code fragment above is still 
in the CVS. But as i said, my C++ skills are very basic and I do not if 
one just can remove these lines without disturbing something else
