Hi,
I'm currently struggling with lnb-sharing on my budget-only system (Samsung SMT7020 internal DVB-S together with an USB-based Opera S1 DVB-S device). This is running vdr 1.6.0 with the vdr-extensions patch 58 (with lnb-sharing and syncearly only) and softdevice (cvs from February 20th).
I can watch live TV fine for a few seconds/minutes, but then the picture freezes. I asume this is because the free dvb-device does it's transponder scans and switches to a wrong polarity/band.
Both devices are configured to use the same LNB:
root@samsung:~# grep LNB /etc/vdr/setup.conf Card1usesLNBnr = 1 Card2usesLNBnr = 1 Card3usesLNBnr = 3 VerboseLNBlog = 1
The "Card3usesLNBnr" is autogenerated by vdr, and doesn't show up in the LNB configuration OSD menu. Setting it manually to 1 doesn't help.
This is what the log says (note that vdr thinks there is a LNB 9 available):

So it looks like vdr detects that there is a conflict, but switches anyway? I tried to fix all devices to use LNB 1 by hacking the vdr source (to get rid of this LNB 9), but this resulted in "channel not available" for all channels.
Unfortunately I have no clue how softdevice works, but to me it looks like vdr thinks it has an exclusive LNB which it doesn't have to share.
Does anyone run lnbsharing together with softdevice successfully, or am I wasting my time on this?
Thanks,
Andreas
