  Hi!

 Now that I have a spare DVB-S2 tuner (TechniSat SkyStar USB HD
(adapter2); the others on this box are atm Hauppauge Nova-TD model
1172 (adapter 0+1) and TechnoTrend S2-3600 (adapter3) - all USB) I
decided to play with vdr device bonding.  I discovered three things:
(still using vdr 1.7.29, I know I should upgrade... :)

1. The LNB setup OSD menu causes bonding to fail (it's trying to
   bond a DVB-T tuner) if I set the two DVB-S2 tuners as "connected
   to sat cable 1"; it works with "sat cable 2".  Maybe it somehow
   thinks of (one of?) the DVB-T tuner(s) as cable 1 too?

2. The infosatepg plugin doesn't check MaySwitchTransponder() and thus
   grabs a bonded device when it shouldn't, I just patched that in the
   FreeBSD port: (plugin maintainer Cc'd)

	http://svnweb.freebsd.org/ports/head/multimedia/vdr-plugin-infosatepg/files/patch-infosatepg.cpp?r1=300896&r2=312357

3. Running with these four tuners (dual DVB-T and the bonded two DVB-S2)
   I get two different deadlocks waiting for cDvbTuner::bondMutex
   after live viewing a DVB-T(!) channel for longer (OSD doesn't
   react anymore and attaching gdb reveals two threads waiting for
   bondMutex) - the following two changes make it work but there
   probably is a better fix:  (patch may apply with offsets; one
   of the problems I think is a lock order reversal with cDvbTuner::mutex
   and bondMutex when cDvbTuner::SetChannel calls back into itself
   with bondMutex held.)


 Thanx,
	Juergen

What does the "Setup/LNB" menu look like on your system?
Does it list only the two DVB-S devices, or all four of them?
Which device numbers does it display?

What does the "DeviceBondings = ..." line in setup.conf look like
in both cases (working/not working)?

You wrote that your DVB-S2 device is "adapter2". Does this mean it
is actually "adaper2/frontend0" and "adapter2/frontend1"?

Have you appliead any patches to VDR?
If so, what happens without them?
Same for plugins.

 No the other DVB-S2 tuner is adapter3 (TechnoTrend S2-3600), all four
only have frontend0 no frontend1.

 Currently the two patches belonging to the iptv and ttxtsubs plugins
and my stb0899 signal strength patch, and of course the FreeBSD
portability patches.

 I will have to check that later tho I guess they are unrelated...

 I just started vdr with just the xineliboutput plugin (I don't have
an ff card) and got the same

DeviceBondings = 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

when setting both DVB-S2 tuners as ".. connected to sat cable 1".

 I wonder, could this be a result of me running vdr with only the DVB-S2
tuners once and the first 1 in DeviceBondings that I may have set then
simply doesn't get reset when the first two tuners became DVB-T?

Just one more thing: did you get any log messages regarding device bonding
when it didn't work?

I was a little cnfused about this at first ;-)
Will look into it later.

BTW: you sent your original posting "To" me and "Cc"d the VDR-ML. Therefore my reply
inadvertently only went to you and not to the list. I'm no replying explicitly to the
list. Please send postings only to the list and do not Cc me (unless you only want to
contact me privately).

Sure, I just reproduced it:
