I have:
Internal:
Tuner A (dvb-c)
Tuner B (dvb-c)
USB:
Tuner C Set to (dvb-c)
I have a splitter already. In the start I tried to make a loop from A -> B -> C. That did not work.
Now I have the splitter setup like this:
1 output to Tuner A -> B (Works fine when Tuner C is not enabled)
1 output direct to Tuner C (works fine, but when connected it makes Tuner B Fail!)
I use all updated (today) OpenPli 4.0 as well.
I will try to contact you on SKype - right now I have to see Brasil - Mexico, though I really would like to have this working.
I will contact you guys - Can it be thursday evening maybe or when fits you best ?
