Description

There are some cards (eg TBS-6508) that support DiSEqC only on the master tuner but not on the salve tuner. This might be enough for legacy LNB setups, but in case of Unicable LNBs it logicaly does not work. Would it be possible to alter the behaviour of a slave tuner to not check for compatible settings when set up with a Unicable LNB and use the master tuner to send the DiSEqC unicable message instead?

Keep up the good work

I'm currently trying to convince TBS to fix this on the driver side. I also came across another potential issue with Unicable devices (although I'm not yet 100% sure if my assumption is correct. If each tuner is running in its own thread there could be two devices sending diseqc commands on the same cable at the same time, which would result in garbage. If that is the case then we would have to implement a semaphore to avoid this situation if Unicable LNBs are present.

I was wrong about the collisions, it is already taken care of in src/input/mpegts/linuxdvb/linuxdvb_en50494.c
