So this one works as well, great! But which one is it?
Please tell me the minor device id. I need to use it to separate the 2 sections.
i will need to control the other one in a very different way.

Hm, i didn't have any compile problems ...

Why? the cards should be autodetected. Or is there a variant of the 948 with
a device id different from 16be:000d?
It should be possible to give a list to the use_frontend=xx option.
Something like use_frontend=0,1,0 which should select DVB-S only for the
2nd instance. Am i wrong?
Of corse you will need to select the right frontend which is not easy with
some applications.

But thank you for your fast reporting!

Another issue: You have some patches waiting for integration. We can use
my other repository for this.

Best regards
