Yes, this whole discussion for which there is no simple solution.
The good part is that not many ppl have dvb-s only cards.
However this discussion is different that the lnb share feature from the title for which the fix will be implemented in 0.5 by marking adapters as slave (-S) and allow them to set only the frequency of the tuner.
BTW you can open a new enhancement about a good way to choose the DVB card based... I think think we can still discuss about this.... and u can write what u think... I think the only requirement is to choose the adapter BEFORE the tuning...
Short question: With the last commit is possible to use one old DVB-S tuner (version 1, not -S2) connected to the same wire as slave tuner? Will the minisatip use the correct tuner based on DVB-S or DVB-S2 transponders?
