[mythtv-users] Problem MythTV 0.20 and DVB-S Diseqc Settings

Wed Sep 27 06:48:27 UTC 2006

Hello,

I'vw some problems with mythtv 0.20 on a Gentoo machine in conjunction
with my DVB-S equipment.

Here is what I have:
- Haupauge Nova-S
- Diseq Switch with 2 LNBs possible, but only one connected
- Universal LNB looking at Astra 19,2

What I have configured:
- DVB-S Card
- connected to a DISEQ switch with 2 ports
- At port 1 of the switch is a LNB Universal Europe configured

Here is my problem:
- Scanning for channels in mythtv-setup works
- Most SAT Transports don't work in mythtv

For example "Sat.1" works, but when I tune to another Transport ID on
which is "ZDF", I only see biterrors at the frontend in the GUI. Switching
back to the original transponder and everything is ok.

Here is an example output of mythbackend (channel debug):

The first tuned channel work, the second don't work. Switching back to
first channels works.

Any suggestions? Do you need some information out of the database?

Thanks in advance
