No Lock on some transports with Hauppauge WinTV-HVR4000 (DVB-S)

[Björn Tantau <svn.mythtv.org@…>]

I'm using a Hauppauge WinTV-HVR4000 DVB-S/S2/T/Hybrid with

$ mythbackend --version

When I scan for channels with DVB-S I can get a lock for some transports (10743750 H DVB-S (QPSK) - 22000000 5/6) but for others I can't (12544750 H DVB-S (QPSK) - 22000000 5/6).

I have no problems locking to these transports (and watching the channels) with szap or kaffeine.

I already tried the kernel patch mentioned in #7198 but it looks like my problem is different.

I'll attach a log from mythtv-setup.real with --verbose channelscan,siparser,channel,record,extra where I first tuned to a non-working transport and then tuned to a working transport.

Maybe it is the same bug as ​http://svn.mythtv.org/trac/ticket/7292, you could try installing the patch like descibed here:

​https://bugs.launchpad.net/mythtv/+bug/439163/comments/51

Till now this fixed it for HVR 1300, 3000 and 4000, so i hope it fixes yours, too.

[Björn Tantau <svn.mythtv.org@…>]

I already tried that without success. But I will leave a comment at ​https://bugs.launchpad.net/mythtv/+bug/439163, perhaps my bug is related after all.

I feel really dumb, the ticket can be closed. I wasn't aware I have a DiSEqC Switch. I thought I'm connected to the LNB directly. After I set up a Switch with one LNB I could scan every channel.

Works after configuring switch. Thanks for the followup.
