Sorry forgot to metion the tuner config....
I tried these 2 settings both with the same result:
1. Tuner B same as Tuner A
2. Both individual
Yes I got that the first tuner is always active for the TV screen. But even tough i just can stream exactly the channel with is on tv screen. (without enabling the "zap before stream" option)
Thanks for the tip with the standby. If the box is in standby i can stream 2 different channel via openwebif.... (can't test kodi right know).
